Clojars Design Update

Howdy Everyone,

/cc @technomancy @wstrinz @losingkeys @micfunk @missingdink

A couple of us at @bendyworks had some spare time on our hands. I spoke with our designers and a bit with @technomancy and got a clojars.org redesign moving. We have no doubt there will be small design changes and fixes here and there, but given the way the last redesign PR effort went, let's keep this conversation scoped as tightly as we can.

@ato && @xeqi -- I haven't seen you guys on IRC, but I've chatted a bit with @technomancy. I think what we have here is a nice improvement. We hope you agree.

Notable Changes:
- The pages are (for the most part) responsive.
- Color scheme revamp
- Typography revamp
- Layout changes on several pages, specifically the dashboard and jar info pages.
- Fat and skinny header -- fat displays only on the homepage.
- Other miscellaneous tweaks and changes. See attached screenshots.
