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
Weirdly everything about this call has the plural - it's an easy fix and makes it consistent, so will update it.
