Login box is messed up

Well, that's annoying. The rebeldroids theme doesn't inherit from the global theme for all of these things. Apparently they rethunk the "modal" dialog and it needed a new class, so I've added that and it behaves now

But... There's a lot of churn in even just the global css, I'm not sure how we're supposed to merge that/import that to our droids theme

I guess I'll just ignore the problem for now, but if folks notice funky layout that's changed or broken, please let me know.
