Deployment target metadata

The feature you've all been waiting for! Or some of you. Maybe just me...

This adds metadata to the UI and gives you the ability to refresh it manually. Scott has (more or less) seen how it looks, and I paired with Alex to barf out all that CSS.

I've found one issue that I need to address:
  * [ ] Created at displays in UTC
  * [ ] Flash notice on successful refresh
are these doing anything other than supporting your dom_id_selector business?
