Add optional signature in xmonad.hs

I thought I had to do this during some debugging session, but the actual
problem was elsewhere.
Updates to neobundle
Add arcanist to path (ie for ghc development)
Move out rsync commands
Add rsync-repos-generic

I use it like this now:

    rsync-repos () {
      local src=~/spotify/repos
      local dst=/home/arash/spotify
      rsync-repos-generic $src $dst $@
    }
Allow optional qualifier in rsync-repos
Add more PATH variables
Add rectangle toggle to tmux
Remove python mode, I don't know what it does
xmonad: Fix the gmailInFirefox shortcut
