Add inventory sorting buttons based on name, attribute, and set (armoire):
- Each gear[klass] has its own sorting buttons and sorting state including costume classes
- The attributes sort descending when selected, then by sum of all attributes
- There is no default sort
- The armoire also sorts by set which sorts by item[set] descending, it does not sort within a set (ex "1 of 3" vs "2 of 3")
- Name sorts by .text() ascending
