Finally removed MapsManager!

The game won't scroll (and thus won't spawn) anymore, and fancier macros
like Pipes and Scenery aren't working, but that's ok.
Fix for patterns from FullScreenMario

Height for scenery is given as [1] when they're stored as quick arrays,
so this accounts for that now. It's glorious.
Fix for screen not scrolling

It looks like characters are being spawned too quickly now, but the
screen does scroll.
Fix for spawnMap

Turns out, hardcoding .spawnMap(7000) in setMap isn't a good idea. Who
would have thought?
Removed some old upkeep references

Also removed the console.log("Spawning"...).
Fix for spawnMap not activating cycles

Thing.onMake wasn't being triggered because I accidentally removed the
code, and because the first .spawnMap was before the TimeHandler reset.
