Added a new auto-fix for actors atop bombs in CCL levels

This fixes CCLP5 level 25 (and I think one or two others) by introducing
a new item, the dormant bomb, which turns into a regular bomb when
something moves off of it.

Other accumulated tileset touchups that snuck in:

- Recolored the canopy to hopefully look more like a tent
- Lightened slime by one shade
- Made the custom green floor colors clash less, and lightened the
  yellow floor grout
- Removed the shadow from the pause stopwatch, and lightened the other
  two, to better distinguish their different behavior
- Added little rivets to steel walls
- Made the symbols on the sokoban blocks easier to see
- Lightened the blue and red keys to match the shade of the other two,
  and also hopefully make them easier to see atop water and thieves
- Shrank the railroad crossing sign slightly
- Added laces to the hiking boots
- Added shading to the bowling ball
- Removed the shadows from the actor versions of the bowling ball and
  dynamite
- Darkened the dynamite item to better distinguish it from active
  dynamite
- Lightened the blue teleporter exit so it doesn't look too much like an
  inactive red teleporter
- Improved the gradient on the beetle
- Made the hint tile look recessed like CC2, to better convey that it
  blocks some actors
- Added art for some possible tiles: rainbow teleporter, toll gate, nega
  heart, phantom ring, feather
