Initial console integration

Before this grows anymore I think it would be good to merge it in, and then build on it in smaller pull requests.

This adds a new Inspect tab, with the console UI parts. The console widgets are converted to knockout.

The Run tab is left unchanged, and the integration currently piggy backs on the sbt-atmos integration there. Updating this to having the analysis running within activator and sending trace data there would be good to do on its own.
