SCUMM: Maniac V0: Implement the original Walk Code (to fix some anim glitches), fix opcode to use _moving correctly (as V0 is different)
SCUMM: Maniac V0: If boxes are neighbors, walk directly to the new box. Remove extra call to 'animateCostume'. Remove now unnecessary V0 walk calc functions
SCUMM: Maniac V0: Correctly handle 'slanted' walk-boxes, Add new variables to save-games, Bump the SaveGame Version number, remove obsolete V0 code in V2 functions
SCUMM: Maniac V0: Remove workaround for bug #2971126 (this issue no longer occurs as walking is handled the same as the original)
Merge pull request #539 from segrax/master
