Add Inventory

[kihashi]

Often, I turn in items in batches, so I gather lots of items in chests before turning them in. Sometimes, I lose track of which items are turned in and which have yet to be turned in.

Add an inventory system:

• [ ] Add and subtract an item from inventory
• [ ] A page to show items in inventory
• [ ] Add inventory number, plus and minus button to item cards
• [ ] When marking an item as completed for a bundle, subtract that item from inventory.
