Styled the admin interface.

The design goals were:
+ Authoritative
+ Calming, or at minimum not panic-inducing
+ Ability to operate with no prior instruction

I'd like to add in the status data as placeholder, but I wanted to get this up before figuring out how to access the document's properties for that purpose.
