Tons of changes to correct the position of event animations in a slightly prettier way than the previous way.
This time the offsets within animations aren't changed. Instead the offsets are changed for each event.

bonus.cpp
*) Changed the method call that disables a default animation offset.

anim.cpp, anim.h
*) Removed method to copy offsets.
*) Refactored method name for the method that disables a default animation offset.

levelload.h
*) Changed the enemy path loading

bridge.cpp, event.cpp, eventframe.cpp, event.h
*) Changed method calls that happen with certain behaviors
*) Added an extra offset that can be set to correct positons.

playerframe.cpp
*) Changed code to understand the extra offset
