Got Conveyer belt to animate; not animating fast enough. May need to
redo the number of frames per second and change around tick rates to get
objects animating at the right speeds. That's a tweak for a later time.
Fixed an issue where bonzo would fall through a block if there was only
one block, he was flanked by air on sides, and he was standing in the
middle. Algorithm for checking if he was on the ground did NOT account
for the need for multiple centres, or centres at all.
Completed conveyer belt physics, although this reveals an issue where
slamming into a wall at high speed causes you to 'land' in it. 

Fixed an issue where it was almost impossible to jump through 2 thru
blocks flanked by solid blocks without pixel-perfect precision. Added a
'special case' that 'snaps' bonzo in place to do the jump if he is close
enough.

Changed bonzos speed from 2 to 3. This may be a bit fast. The ideal
speed would be 2.5 but it seams some integer conversion is preventing
incremental speeds of this nature (he would move faster to the left than
to the right due to truncation). Must find source of truncation so his
speed can be tuned.
