Remove unnecessary dependance on Pyglet

Pyglet window events don't need to be explicitly dispatched because SyncGenerator runs in a separate thread. Remove these lines because they create an unnecessary dependance on Pyglet being imported in the class (which causes the emulator thread to quietly die and no emulated sync pulses to be generated!)
