[3.1.0] De-crudify the ConfigSchema space; we're starting over again

- Optimize ConfigSchema by removing non-essential runtime data. We can probably optimize even more by collapsing object structures to arrays.
- Removed validation data from ConfigSchema; this will be reimplemented on Interchange
- Implement a sane Interchange composite hierarchy that doesn't use arrays
- Implement StringHash -> Interchange -> ConfigSchema, and rewrite maintenance file to account for this
