Changes from 0.4.0 to 0.5.0

• Number pad keys mapped to relative positions on the menu.
• Item icon can now be any character.
• Fixed: Enter key activates an highlighted item.

Known bugs

• Exceptions thrown while menu is open and then caught by a python debugger will freeze out the mouse and keyboard. The only way to unfreeze them is to login on either a text console or remotely and kill the python process with the open menu (eg; Ctrl-Alt-F1, ps -A, kill -9 NUM_OF_LAST_PYTHON_PROCESS).
