Fix Prize for the Reckless moving platform losing its block when...

Browse Source 
...you die and the platform's x-coordinate is to the left of x=152.
Which means if you die and the platform isn't completely clear of the
space of its adjacent disappearing platform.

The block needs to be updated accordingly with calls to
obj.nocollisionat() and obj.moveblockto(), else the block will simply be
left behind and the platform will no longer have any collision. This is
in contrast to 2.2 behavior, where the platform would simply
unconditionally create a new block, which would actually end up with a
duplicate block since the previous block didn't get cleaned up, but this
didn't cause any problems because the room was carefully designed so you
would never be able to touch that previous block after you died and
respawned at the checkpoint. But it's still there.

I also added comments to document what this kludge code did, because
otherwise it would be mysterious to readers who are unfamiliar with it.

Fixes #543.
