[emacs] Use nxml-mode's electric slash rather than my own code.
[emacs] Add “menux” notmuch view.

Theso are Linux related messages sent to me.
[sawfish] Use “music” script to control music playback.

At times, instead of using MPD, I use Spotify to listen to music.
To be able to control both with the same interface, this commit
creates a “music” script which detects whether Spotify is running
and either issues Spotify or MPD commands.  This commit adjusts
Sawfish configuration as well, to use this new script.
[shell] Use colours in less output.

This mostly affects man pages.
[xlocker] Added script for running xlock.

Other than running xlock, this script also pauses the music if it is
playing (and appropriately turning it back on once xlock terminates)
and forces screen off.
[emacs] Remove fill column indicator.
[git] Move git stuff to separate directory.
[git] Add .gitalias file.
[xinitrc] Log messages to /tmp/sawfish-log.
