prototype-put-site-name-in-the-dockbar

Hey Nate, this is a prototype I've been brainstorming about with Julio and Sergio. The idea is to move the Site Name when in Site Administration to the top bar, along with 'Site Administration'. We think it makes sense semantically and allows gaining quite some space. I like the result although I think it needs a couple of details to be fixed: 1) The chevron that separates the site name from 'Site Administration' is too large. 2) There is a padding in .aui .wrapper of 1.1em that is not desired after this change, however we cannot just remove it. We should think of an alternate way of adding it when it's really needed. 3) I'm not 100% sure about using bold for the Site Name. Julio mentioned that it might be better to use some color instead.
