feature: comparing two different gear sets easier

[ShyShys]

healer gear planner has a way to compare and change two sets side by side, having this feature on xigear would be poggers. 👍

This functionality already exists, you would just add two (or more) sets to the same sim. It's one of the primary use cases of xivgear.

We talked about it elsewhere, the specific ask is being able to see the items, materia, etc of two sets at the same time.

What I'll probably do for it is add a button that opens a popup with a set editor.
