anim.h, anim.cpp
*) Frame by frame X-offsets are being shifted two bits up now.
*) The animation-wide X-offset has been removed because it does not exist.

levelload.cpp, bonus.cpp
*) Due to the changes in anim.cpp and anim.h the animation loading code had to be changed.

bridge.cpp
*) Bridges should ignore an animation's Y-offset if it is zero.

event.h, event.cpp
*) Added a getAnim method to make life easier.
*) Events with certain behaviors need some fiddling with Y-offsets so they can be drawn correctly.

playerframe.cpp
*) The invincibility animation should also ignore Y-offsets.
