Changes from 0.7.0 to 0.8.0

• Rewrote item handling code to use plain angles instead of an array of points.

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).
