Update Emacs packages

This is a massive diff that I had to do in a hurry - when leaving
Urbint. I'm pretty sure that most of these are updating Emacs packages,
but I'm not positive.

+;;; Commentary:
+
+;; Alert is a Growl-workalike for Emacs which uses a common notification
+;; interface and multiple, selectable "styles", whose use is fully
+;; customizable by the user.
+;;
+;; * For module writers
+;;
+;; Just use `alert' instead of `message' as follows:
+;;
+;;   (require 'alert)
+;;
+;;   ;; This is the most basic form usage
+;;   (alert "This is an alert")
+;;
+;;   ;; You can adjust the severity for more important messages
+;;   (alert "This is an alert" :severity 'high)
+;;
+;;   ;; Or decrease it for purely informative ones
+;;   (alert "This is an alert" :severity 'trivial)
+;;
+;;   ;; Alerts can have optional titles.  Otherwise, the title is the
+;;   ;; buffer-name of the (current-buffer) where the alert originated.
+;;   (alert "This is an alert" :title "My Alert")
+;;
+;;   ;; Further, alerts can have categories.  This allows users to
+;;   ;; selectively filter on them.
+;;   (alert "This is an alert" :title "My Alert" :category 'debug)
+;;
+;; * For users
+;;
+;; For the user, there are several variables to control when and how alerts
+;; are presented.  By default, they appear in the minibuffer much the same
+;; as a normal Emacs message.  But there are many more possibilities:
+;;
+;;   `alert-fade-time'
+;;     Normally alerts disappear after this many seconds, if the style
+;;     supports it.  The default is 5 seconds.
+;;
+;;   `alert-default-style'
+;;     Pick the style to use if no other config rule matches.  The
+;;     default is `message', but `growl' works well too.
+;;
+;;   `alert-reveal-idle-time'
+;;     If a config rule choose to match on `idle', this is how many
+;;     seconds idle the user has to be.  Defaults to 5 so that users
+;;     don't miss any alerts, but 120 is also good.
+;;
+;;   `alert-persist-idle-time'
+;;     After this many idle seconds, alerts will become sticky, and not
+;;     fade away more.  The default is 15 minutes.
+;;
+;;   `alert-log-messages'
+;;     By default, all alerts are logged to *Alerts* (and to *Messages*,
+;;     if the `message' style is being used).  Set to nil to disable.
+;;
+;;   `alert-hide-all-notifications'
+;;     Want alerts off entirely?  They still get logged, however, unless
+;;     you've turned that off too.
+;;
+;;   `alert-user-configuration'
+;;     This variable lets you control exactly how and when a particular
+;;     alert, a class of alerts, or all alerts, get reported -- or if at
+;;     all.  Use this to make some alerts use Growl, while others are
+;;     completely silent.
+;;
+;; * Programmatically adding rules
+;;
+;; Users can also programmatically add configuration rules, in addition to
+;; customizing `alert-user-configuration'.  Here is one that the author
+;; currently uses with ERC, so that the fringe gets colored whenever people
+;; chat on BitlBee:
+;;
+;;  (alert-add-rule :status   '(buried visible idle)
+;;                  :severity '(moderate high urgent)
+;;                  :mode     'erc-mode
+;;                  :predicate
+;;                  #'(lambda (info)
+;;                      (string-match (concat "\\`[^&].*@BitlBee\\'")
+;;                                    (erc-format-target-and/or-network)))
+;;                  :persistent
+;;                  #'(lambda (info)
+;;                      ;; If the buffer is buried, or the user has been
+;;                      ;; idle for `alert-reveal-idle-time' seconds,
+;;                      ;; make this alert persistent.  Normally, alerts
+;;                      ;; become persistent after
+;;                      ;; `alert-persist-idle-time' seconds.
+;;                      (memq (plist-get info :status) '(buried idle)))
+;;                  :style 'fringe
+;;                  :continue t)
+;;
+;; * Builtin alert styles
+;;
+;; There are several builtin styles, and it is trivial to create new ones.
+;; The builtins are:
+;;
+;;   fringe        - Changes the current frame's fringe background color
+;;   mode-line     - Changes the current frame's mode-line background color
+;;   gntp          - Uses gntp, it requires gntp.el (see https://github.com/tekai/gntp.el)
+;;   growl         - Uses Growl on OS X, if growlnotify is on the PATH
+;;   ignore        - Ignores the alert entirely
+;;   libnotify     - Uses libnotify if notify-send is on the PATH
+;;   log           - Logs the alert text to *Alerts*, with a timestamp
+;;   message       - Uses the Emacs `message' facility
+;;   momentary     - Uses the Emacs `momentary-string-display' facility
+;;   notifications - Uses notifications library via D-Bus
+;;   notifier      - Uses terminal-notifier on OS X, if it is on the PATH
+;;   osx-notifier  - Native OSX notifier using AppleScript
+;;   toaster       - Use the toast notification system
+;;   x11 -         - Changes the urgency property of the window in the X Window System
+;;
+;; * Defining new styles
+;;
+;; To create a new style, you need to at least write a "notifier", which is
+;; a function that receives the details of the alert.  These details are
+;; given in a plist which uses various keyword to identify the parts of the
+;; alert.  Here is a prototypical style definition:
+;;
+;;  (alert-define-style 'style-name :title "My Style's title"
+;;                      :notifier
+;;                      (lambda (info)
+;;                        ;; The message text is :message
+;;                        (plist-get info :message)
+;;                        ;; The :title of the alert
+;;                        (plist-get info :title)
+;;                        ;; The :category of the alert
+;;                        (plist-get info :category)
+;;                        ;; The major-mode this alert relates to
+;;                        (plist-get info :mode)
+;;                        ;; The buffer the alert relates to
+;;                        (plist-get info :buffer)
+;;                        ;; Severity of the alert.  It is one of:
+;;                        ;;   `urgent'
+;;                        ;;   `high'
+;;                        ;;   `moderate'
+;;                        ;;   `normal'
+;;                        ;;   `low'
+;;                        ;;   `trivial'
+;;                        (plist-get info :severity)
+;;                        ;; Whether this alert should persist, or fade away
+;;                        (plist-get info :persistent)
+;;                        ;; Data which was passed to `alert'.  Can be
+;;                        ;; anything.
+;;                        (plist-get info :data))
+;;
+;;                      ;; Removers are optional.  Their job is to remove
+;;                      ;; the visual or auditory effect of the alert.
+;;                      :remover
+;;                      (lambda (info)
+;;                        ;; It is the same property list that was passed to
+;;                        ;; the notifier function.
+;;                        ))
+;;
+;; You can test a specific style with something like this:
+;;
+;; (let ((alert-user-configuration '((((:severity high)) momentary nil))))
+;;   (alert "Same buffer momentary alert" :title "My Alert" :severity 'high)
+;;   (alert "This is a momentary alert in another visible buffer" :title "My Alert"
