MoveStack patch

This plugin allows you to move clients around in the stack and swap them
with the master. It emulates the behavior off mod+shift+j and mod+shift+k
in Xmonad. movestack(+1) will swap the client with the current focus with
the next client. movestack(-1) will swap the client with the current focus
with the previous client.
