Hide *tramp..* buffers.
Swap <f1><f2> and <f1><f3> bindings.
Add git-messenger package.

Handy: show the commit message for the current line.
Only enable ws-butler for file buffers.
Load optional ~/.emacs.d/local.el.

Need a place to stash random project-specific stuff: temporary named
macros, etc.
Rework ibuffer filters/groups.

 - Add ibuffer-tramp package to group buffers by tramp connection.
 - Add some filters for seeing files, modified files, remote files.
 - Remove a bunch of groups not currently used.
