Subject: Add clickable workspaces to XMobar.

This is using xdotool to send a keystroke, which is not the best way to
do this. In fact, a proper server protocol would be better, but this is
how it is at the momement unfortunately.

There is a problem where trying to use xdotool to send a key for a
multibyte character will cause all events to freeze on XMonad for some
reason, so these actions are guarded so only 'a-zA-Z0-9' are clickable
and the rest are not, which is /okay/, I don't use unicode workspaces
that often.
