Support Vim, Tmux, Emacs with Stow

After moving off of Meta, Dotfiles has a greater responsibility to
manage configs. Vim, Tmux, and Emacs are now within Stow's purview.

+;;; Commentary:
+
+;; Minor mode for flowtype.org, derived from web-mode.  Essentially a
+;; rewrite of an official flow-for-emacs snippet into a standalone
+;; mode with an improved usability.
+;;
+;; To enable this mode, enable it in your preferred javascript mode's
+;; hooks:
+;;
+;;   (add-hook 'js2-mode-hook 'flow-minor-enable-automatically)
+;;
+;; This will enable flow-minor-mode for a file only when there is a
+;; "// @flow" declaration at the first line and a `.flowconfig` file
+;; is present in the project.  If you wish to enable flow-minor-mode
+;; for all javascript files, use this instead:
+;;
+;;  (add-hook 'js2-mode-hook 'flow-minor-mode)
