Add new MouseCursor interface for setting the mouse cursor.

Remove most of the old cursor control interface. This keeps backwards compat for CursorControl.SetCursor (which just redirects to the new function) to kepe existing users running. None of the other functions on cursor control were implemented, so I removed all the proxying and stuff for them.
