some fixes for the platform moving on the X axis, still needs some tweaks, mainly player need to move with the platform a bit after leaving it, carrying the x_vel of the platform doesn't seem to be enough.  Also need to fix player warping on top of platform when collidiing with sides, this may be a non-issue in actual gameplay as most horizantally moving platforms will be drop-down type.

Also made some tweaks to the 'fat_mask' for detecting walls when airborne, still needs more polish, also found that the normal wall detector needs tweaking, need to nail down final images for player to make them 'perfect'
