More consistent font stacks in default and backstage

[ListenerJubatus]

I have a Windows 8 PC and a Mac. Presumably, the Mac doesn't have the full Segoe UI font family, meaning that the Backstage is rendered in glorious Times New Roman.

Yet, the default forum theme does have Arial as a fallback, but just Arial. It's a little inconsistent. I'd personally go Segoe UI Light, Helvetica, Arial, sans-serif.

Or, Roboto as a web font; especially given that your default style actually does sort of look a little Android-ish, and it's got a whole suite of styles.

But I love Times New Roman. 😛

I'll change it to be more consistent.

Try out the latest update, in case Segoe UI can't be found, it will now use Open Sans from the web (and if that fails Helvetica, Arial, sans-serif). Better now? I don't have a Mac to test.
