(DEV????) Improvements to inventory.

[Raikki]

By coincidence I'm actually out chopping trees and chipping rocks right now, and to have enough room I have to leave 3/4ths of all my gear on my retainers so it's a huge chore if I want to transition to combat in particular. I'd love to have separate equipment and non-equipment inventory limits.

I actually had to tell someone the other day, "I'd love to synth that for you but I don't have enough room in my inventory to even hold the parts for it."
