Added ability to rename features

I'm not completely satisfied with this, but wanted to get it open sooner rather than later. I'll leave a few inline comments. The branch obviously won't build until we do something with `IvoryT` (I really wish you could re-target PRs in GH)

I agree with this. But we should call it out really clearly call it out next time we are together to let everyone know we should be pushing to categorize these commands (and maybe add a card to do the existing ones in a single hit).
