Changes

Fix not marking the original folder as scanned

It would detect it is scanned with later logic, but might as well do it immediately to allow set lookup instead of string building comparison

Switch to simplier dynamic texture loading

After some empirical testing, in most cases listResources was slower than hasResource
That said, hasResource is slower than a hash lookup, so since I already have the logic to build and clear the cache, use that to cache the result of hasResource.

Improve spilling effects

Most metals now have a spilling effect beyond fire damage + set fire, lots of them are loosely inspired by mistborn
Added two new spilling effect options: add insomnia and add breath
Mob effect spilling effects now enforce its milk curable
Added new repulsive effect, inverted magnetic for mobs
