Animation stuff

Back from China a couple days ago, didn't get to touch this much over there since I didn't have much free time and the internet was maddddd iffy. Anyhow since I got back I've created a working animated sprite class family and did some work on tile collision. The animated sprite takes images from a sprite sheet that ImageLoader splits up into frames and displays each frame based on a timer. Also, it can display the animation according to the direction of the object, so if a character is running to the left it will show the left facing animation. I also added basic undo and fill-all features to the map editor.

A random map from the map editor. You can't see the running animation but trust me it works :)
