New attempt at fixing shit. Also some sprite stuff.

-Messed around with another air proc I saw runtiming on server.
-Attempted to fix overlays even further. Test run successful but you never know with random chances that hopefully are now as low as the test run let me see.
-Meddled around with transit space. 2 directions were missing a corrective step against negative rng output.
-Added otie snouts.
-Improved contrast in the corvid markings.
-Added tail wag sprites for husky and otie.
