Subject: Use ENV[EDITOR] if possible

Defaulting to EDITOR, then checking for the mate command, and then using
vim as a last resort.

Signed Off By: Max Howell <max@methylblue.com>

Plain brew edit still uses Textmate though because a client that
supported a project concept is required for that particular feature.
Patches for that welcome.
