Allow Filters from Any Style to be Used in all Styles.

Currently many filters are not accessible if you are not in the correct style. If i want to use doom and gloom or corrupted essence is a world map or scifi map its currently not possible.

For example, things like 40K, Delta Green, Call of Cthulhu, Vampire the Masquerade and numerous other RPGs have horror themes in modern and scifi settings. Having them available for all styles makes the most sense. Whether i want to make a world, region, city, or battlemap.

There is no reason to lock them to a style. We have access to all other asset types (strokes, textures, stamps), why are these locked.
