* unify stat handling. If there are discrepancies left at least they are now centralized.
- health should no longer pretend to be mana
- stats are no longer capped to 32.7k points as items can have multiple of the same stat and handily exceed smallints
* weight scale fixes:
- "repair cost" is no longer a weight scale option. Why was it one in the first place? Also it wasn't even accessible before. (that was a bug)
- "bonus armor" is now searchable and only applied to armor pieces
* removed unused parsed stats from itemsets
