* E_MetaTableFromCfg added for wholesale conversion of a cfg_t with basic fields to a MetaTable, with optional prototypical inheritance similar to JavaScript. Not currently recursive or supportive of list-type options, as not anticipated to be needed yet.
* Generalized MetaTable hash growth so it can apply to the MetaKey table. 
* Added new version of inventory module based on a new development plan.
