Refactor ModVersion into Mod and ModVersion

* Remove V1 of the mod version parser and shift V2 up to be V1
* Add a parser for mod.cg files, and refactor the the mod-version.cg
  files to push the appropriate content up to the mod.cg
* Remove the concept of "silent" from BaseModel along with logging
  each event as they are fired (which is what really prompted the
  need for it in the first place)
* Move use of the Storage class to be completely the province of the
  controllers most closely related to models affected
* Convert the ModVersionController to the ModController and have it
  take on responsibility for choosing the mod version
* Update BaseModel to support simple accessors for the current state
* Update CraftingPlan to be able to remove uncraftable items
* Implement the Mod model
