Qt4 Backend Gui Keycode patch

The arrow keys were not being correctly detected in the Qt4 backend of the matplotlib gui code, so I went in and hooked up keycodes for them.

I haven't submitted patches before, but I thought this was worth passing on, so I have attached it. Is this something worth submitting? How would I go about doing that?
