Codebase overhaul. Metaprogram proofread (part 2). Starting to get serious.

Need to rewrite the ps1 lua metaprogram sometime soonish. Getting too bloated... need to consolidate code paths.

In this push codebase structure is starting to get a bit more realized. Decided todo now to match Pikuma's linking module files vods beginning to reorganize its codebase as well.
Atoms & atom components are not in their on *.atom.c files. (Not calling it tape.c as I don't really bake tapes like that outside of the unity c file so far...)

The lua metaprogram has had additional features added to it yet again to avoid hardcoding module handling and supporting multiple atom files per-module.
Either after the camera or cd-rom section I'll be most likely pausing to fully refactor the metaprogram. Possibly as a full re-write to get the loc minimal.
