Disable some code which sometimes makes the player enter walking frames when jumping up to a platform, such as the CEZ3 buttons, despite still being in jumping mode.

If this causes more problems than it solves it can be reverted, but doing a bunch of playthroughs of DSZ1/2, GFZ1, and CEZ3 didn't seem to uncover anything, so I'm tentatively putting it in this branch.
