Implemented first step of DRY for the realtimePages
Added in instant loading via pushing a JSON into the HTML on the builders page

- Removed most of the code for the builders page as we are now grabbing that information from the JSON itself
Added instant JSON for build queue
Added instant JSON for slaves page
Merge branch 'autobahn_instant_load' into autobahn_v1
