Request: add a keyword that means "equippable by my class".

Describe the solution you'd like

This would be similar to the 'meta' keywords in #158. The idea in this case is to make Baganator more fluid between multiple characters.

Assumption: I'm playing a Rogue. While it is currently possible to add "armor & leather" (or just "leather") to a category, that limits the category usefulness.

Idea: add a keyword for 'equippable'. This would be evaluated when Addon loads and alias itself to whatever Armor and Weapon types the character can equip.

This allows creating a generic "My Gear" category that only shows items this character can equip. Then a different category/section can handle all other types.
