[Feature]: Grey/Red overlay un-useable gear

[Toldorn]

Describe the feature

I'd really love it if a plugin available from AdiBags could be implemented - it basically put a red overlay on gear that wasn't equipable on your character (e.g Leather, Mail, Plate on a cloth only class).

Simple, but would make seeing what gear is useful whilst levelling and whats trash without hovering over every item much better.

Describe the implementation

Red overlay on mail if playing a cloth wearer.
