Version 1.3, Pre-Release 4

So I have fixed a lot of bugs in general in this release; and I mean a lot of bugs. There is one bug that makes the player jump back a bit whenever you walk into a mob that is walking towards you, but that will hopefully be fixed in the next release. One last thing, I updated some of the sprites, such as MobAis so you can tell who is a player, until I have actual mob sprites... anyway, enjoy, and report bugs!
