setup.py: use HotKey module (shared with LocationDo) instead of
_StreamVision module

HotKeymodule.c: the aforementioned module

StreamVision.py: use HotKey module instead of _StreamVision module.
Fix StreamVision.displayTrackInfo to not crash when iTunes jealously
hides the names of iTMS tracks from us. Switch track rating keys to
shift-F10/F11 to avoid conflicting with my preferred Expose/Dashboard
key bindings on my iBook.
