* Added Game::runGateProgram()

* Added a separate mechanism to Game to keep track both of the current room number and the next room/gate. Periodically, I check whether the new room differs from the old one and, if it does, I do the change. Doing it any other would is nearly impossible because of the way the original scripts were written.
* Added GPL command Script::newRoom(). Rooms can now be traversed by clicking on their exits. Also, the intro animation partly works. Some parts go by far too soon. I assume this is because the engine still lacks a dialogue GPL command.
* Fixed bug where the gates array of a room was not cleared between uses.
* Save old jump value when we enter Script::run() and restore it in the end (mimicking the original engine).
* Fixed small bug where the gate was supposed to be stored as the first in-game variable and not the room number.
