useful binding for wtftw

[crypt17]

I have written a few useful key bindings that I thought might be of use to you

next_prev_ws() -- move to the one workspace in either direction
next_prev_nonempty_ws() -- same as above but skip empty workspaces
do_warp_mouse() -- warp mouse to current window on focus change

I am currently working on a perWorkspace layout similar to the xmonad one to allow for independent layout lists per workspace

If any of these are of use to you give me a shout.

Joe.
