Add logic for way of the stonefist ascendency

[BligenN]

Fixes "Way of the Stonefist" ascendency not being supported"

Description of the problem being solved:

Stonefist passive was not working - we could paste stonefist gloves all fine, but no automatic transformations would happen

Steps taken to verify a working solution:

• Adjusted mods.lua to generate stonefist mods separately
• Added creation of mod map (original->goal for all glove mods)
• Added per-level parsing to modifiers, had to do a small change to force ui update when level changes.
