/Icon/ Folder cleansing crusade part, I think 4; post-wallening clean-up. (#85823)

Hello everybuddy, your number three rated coder-failure here to clean up
some mess. This PR accomplishes some of the more major structural clean
up changes I wanted to do with /obj/ folder, but decided to wait on
until wallening gets merged, and so, time has come. Several things to
still be done, although I know these cleaning PR's are quite a load, so
will wait for this one to get done with first.

## Why It's Good For The Game
Saner spriters, better sprites, less annoyance. Also deleted a whole
load of redundancy this time around, a lot of sprites which existed
simultaniously in two places now got exit their quantum superposition.
