Reorganize the guild shops

It’d be nice to reorganize the guild shops so I don’t have to sort through a ton of worthless T1/T2 stuff every time I’m trying to find things.

I think the items should be split by tier, with a separate tab for the roster-limited items (XP pots, silver). The current organization makes me sort through lots of junk I will never buy to get to the items I actually want, which are hiding near the end.
