Fixed:

1. Major Bug: Avatar falls through the wall/floor when jumping into a wall at close range.

Also Minor Bugs:
1.1 Point blank jumping into wall shows a frame of the avatar colliding with the wall (no longer shows)
1.2 Occasionally displayed a "No Direction State!" error (was a problem in some of the state changes not taking into account directionless - when the user can press jump without giving a movement command - jumps)
1.3 Avatar would occasionally be repositioned on the wrong side of the wall during wall collisions (it was a problem with the wall collision dection being too smart, and previous code of mine trying to speed up the collision detection by removing some walls from the "collisionable" set by detecting avatar direction.
1.4 Avatar death detection when y travelled was more than 256 pixels was not working at all as intended. it is now fixed.
