Downfall a3

-slightly changed A
-split B ramp into 2 interconnected ramps, point B is now in the middle
-some other small things at B
-slight respawn time adjustments
-slight changes to last
-general changes in healthkits and stuffs

elevator at last is a bit quirky but i dont think thats fixable given how payload collision works

:3

-gutted area from b to c, converted to 3cp payload
-general changes to limit sightlines without choking up the map (most apparent at point b)
-reworked area before last (mirrored + rework)
-mirrored last, general rework (cool new elevator finale!)

1 year procrastination project, wanted to retain what people liked about a1 while fixing the obvious sightline + length issues.
