Improve information on deployment page

This improves the information that appears on the right hand side of the deployment page.

 - Remove blurb explaining what the recent deploy table is
 - Reduce the time window of deploy history to 90 days (previously was infinite)
 - Add build info section and populate when a valid build is selected
Sorry, I'm thinking out loud, as much as anything. I'm just nervous that sharing this resource around could mean that failure in any of these areas could take out the others.
