Robots now carry an internal representation of the LevelStage, updated each update cycle.  This is what the robot 'sees' in the world.
Fixed two errors, both related to issue #2:
1) When a robot is parked on top of a another robot's spawn point, the respawning robot will not respawn.
2) If a robot hits a nasty collision point that makes the robot stay in the world in an unmovable state, its watchdog timer will catch that and reset the robot.
Merge branch 'master' of https://github.com/recardona/game-off-2013
Reduced the watchdog timer to be as quick as possible.  Action sequences of 12 steps take less than this amount, which is why we can't go lower.
