Bootstrappified Wizard Settings modal

I developed this on top of my `nameable_users2` branch that implements a cooler wizard settings modal, so that's where the screenshots come from. For cleanliness purposes I rebased it on coco's master so if my other branch hasn't been merged in yet you won't be able to check the results for yourself. Luckily I brought screenshots :).

This is purely a matter of preference, but now we get the nice glow provided by Bootstrap etc.
