Data Definition Editing API

[Ijwu]

Currently the only method available to mod authors to edit data definitions is to use the mod ppdefmodifier by @tracktwo.

I intend to replicate this behavior to allow for arbitrary, user directed, editing of game data assets. I foresee this requiring these tasks to be complete:

• Develop service for mods which allows for access to and alteration of arbitrary types.
• Develop service for mods which allows for access to and alteration of data definitions.
• Develop a built-in mod which parses files identical or similar to ppdefmodifier's file format.
  • This is for ease of migration for users of ppdefmodifier.

I would like to make this feature set a part of a v0.4 release.
