Chip's Challenge in HTML5 & JavaScript (Bug fixes and improvements)

I've done some bug fixes, additional changes to the map editor and improvements I've been working on fixing for the game. The dirt walls still does not work as they should but yeah, that's just one of those issues I'm having difficulty solving. Maybe someday there will be a fix for that, for now this is more than playable, but although not entirely perfect as usual, I hope someone will enjoy this and give some comments on how well I did on recreating this game from Windows to HTML5 and JavaScript. Thanks ahead of time!
