Inventory Rebuild & QoL

Inventory has now been rebuilt. Less scrolling, more tools and an overall better UX.

Additionally:

• Added "All gear" option to Item Market so you can view all gear types and filter by rarity just as the old version allowed.
• Gear comparison now works in The Forge.
  
• Search Player now shows K/D instead of W/L.
• Variable Rarity items condensed in the Wiki and moved into one section before Consumables, one row each, with the level/rarity ladder opening on tap.
• Added Feed All and Train All buttons to Menagerie.
• Added the total shift counter to Careers mastery tab (X/18500).
