- Added Clothing and Pet buttons
- Updated AccessoriesSelectorDialog to accept slot_filter parameter
- Filter rings by Left Finger/Right Finger slot when selecting
- Store current_left_ring and current_right_ring in loadout
- Display ring effects (multi-effect support) in the UI

Dodge Chance 4%' are now properly displayed.
