Caching _fillable leads to deviant behavior

[alexanselmo]

Caching fillable per room leads to cross-contamination of the filler/replenisher job pools. When it is called multiple times per tick, the _fillable attribute will be cached with the first set of stuctureTypes it is called with, leading to any subsequent calls to return that value, regardless of having a differing structureTypes parameter.
