There have been several times where the unpredictable behavior of a remote player where execute_mario_action() would get caught in an infinite loop. Now we attempt to detect an infinite hang and escape from it. The sequence of actions will be recorded into an errorlog.txt file. In debug mode this infinite hang will cause an assertion to fail, crashing the game. In normal mode the game will break out of it and hopefully carry on normally after new packets come in. I believe this addresses github issue #12 but I can't be sure.
