Separate item names from type/subtype

[Chris Carr]

This requires the addition of "basename": "Whatever" to every object record in object.txt. The idea is that consumable subtypes are actually part of the basename, and not real prefixes or suffixes (e.g. Flask of Oil, etc.). This will make affix and flavour handling neater.

Alternately we can provide a basename only where it can't reasonably be derived from the type/subtype. That is, "basename" would be an optional field for object records.

I believe this is now handled by Kinematics' refactor and the category system. Closing.
