Re-added backlight commands for woodfin.

How did these get deleted. Need a better way to manage autostarts. Maybe in the
install script (if I add this to .files) maybe a autostart.$HOSTNAME file?
Made the workspace switcher window fade sooner.
Added C-S-g hotkey for gmrun.
Removed Ctrl keybinds for backlight. Working OOB now.
Made a new ttmux shell script for tmux terminals.
