Description:

ItemType and the child BlockType class need to be reworked to support tags and materials, instead of lists of materials. These type classes define the logic of each item and block, and must be associated to work with different materials. Tags group materials together in bundles so that they may be easily referenced together, and can be used for this purpose.

Perhaps a major rewrite of this system must be done, with item functions to fix hierarchy issues.
