Add total downloads count to recently pushed jars

Conflicts:
	src/clojars/web/dashboard.clj
Mostly finished redesign

Still todo:
- make sure all flash/error messages are styled
- double check colors & consistency
- fix padding everywhere
- address 'FIXME' comments
  - some of these are decisions to be made, others are just unfinished
    stuff
- remove unneeded ids in favor of reusable classes
- fix the small header on mobile
  - also this hasn't been checked when logged in
- make a search form if the /search route is hit with no 'q' query
  parameter?
- fix the github link on the jar page (right now it just links to
  github.com)
- there's no logo in the redesign at the moment
