Resouce Pack Generation

Allow resource pack generation. Ideal implementation would require some working out, but the overall goal would be to allow font overrides and custom model data based item icons through twilight. Would parse and build a resource pack and provide methods for exporting it as a zip, or web host it (and provide a method for setting a player's resource pack based on the pack object itself when it is hosted). This seems like a harder, long term project, but if implemented well, this could provide a huge reason to use twilight and speed up a lot of development for resource pack-based projects. You can later create items with custom model data and private use area characters fully type safe using the pack object.
