Rogue Runner v0.5.2 - Taking Turns III

For the last few updates, I worried about one enemy that the player takes turns against.

In reality, there will potentially be more than one enemy in a room (or none). So the turn system needs to be able to deal with all those eventualities.

So, now, the player moves and then the game will cycle through the enemies one at a time. Eventually they will do stuff but at the moment they flash to show they are going through their turns.

Note: still no bulid for the moment. One more piece to add to v0.5...
