add part of the wiimote logic
add quitgui() to the gtk thread to try to land the drone when the gui close, but doesn't work... I need to work on this. Tested the wiimote logic to see if everything work as expected and obviously not. At the moment everything compile, but the score logic doesn't detect if the drone has been wounded...
add mutexes for drone_wounded and enemy_wounded variables. Use one of the mutex to share the drone_wounded between the wiimote thread and the score_logic thread. Now it seems to work, but it is really hard to hit the drone. Need further testing.
add some sleeping time inside the wiimote thread and the score_logic thread. Now works fairly well
