Adds to xmonad config music controls
Adds to volume shell script and creates desktop notification script "notify"

Changes xmonad to use volume hotkeys that display notifications
Adds shell script to control mpd playback and create desktop notifications
Replaces ncmpcpp with mpc usage. Creates .xinitrc service to notice mpd seeks

ncmpcpp and mpc are both command line interfaces to mpd. ncmpcpp is interactive,
whereas mpc is command line. Earlier I had used xmonad hotkeys and a script
$HOME/bin/musicPlayback to change songs and display the current song; however,
it did not detect natural song changes in the mpd playlist itself.

  mpc currenty --wait

blocks waiting for song changes and when used in an infinite loop is a more
complete solution. So now the 'musicPlayback' script simply displays the current
song.
Adds ncmpcpp (mpd client) config
Adds emacs configuration. Edits profile.d, xmonad settings for emacs keys.
Adds tmux configuration. Changes volume to accomodate tmux.

My tmux configuration shows the volume. The 'status-interval' tmux option
may have been an ok option to poll for volume changes every X seconds, but a
better, interrupt-driven solution is to tell tmux to update the status bar
whenever I change the volume.
Adds to xmonad config a backlight fade
Modifies urxvt settings to not save lines because tmux does
Adds to mplayer heartbeat command to disable screensaver druing movies
Changes the keyboard to replace caps with another ctrl, esc back to top-left
Fixes mispelling of shell script name
Makes mpd a user background task instead of systemd service
