Subject: Define notmuch KBDs

Until I have more opinions about my workflow with notmuch, I will redefine the
KBDs from Gmail that I'm comfortable with. While not many KBDs are defined here,
evil-collection defines dozens, many of which I find reasonable; those that I
disagree with, I've unbound in this commit.

Composing emails in notmuch feels similar to writing a commit message with
magit. I want to be able to type :x or :wq, but these commands don't DWIM. For
magit, I'd like that behavior to be the same as `C-c C-c`; not surprisingly, for
notmuch, I'd like the same.

I've bound :x to do this for notmuch. I'd like to define a macro that can easily
define buffer-local evil-ex commands for particular modes. This should lower the
cost of defining evil-ex commands and hopefully convince me to support some of
this desired behavior.
