Closes #5 #15
overview: Remove command statistics.
overview: Cosmetic changes.

* Don't pass unresponsive to the view, access config[] object instead
* Remove the statistics header, it only takes up space
* Lowercase a few things
* Change the descriptions for 'radiator' to make the math work: Because
  of how PuppetDB's aggregate-events-count works nodes with both
  successful and failed events count for both causing success + failure
  + unreported to not equal population, which is weird. Now we're simply
  stating that they have failed events instead of saying that the node
  is succesful/failed.
We now require PuppetDB 1.5 / API v3.

PUPPETDB_API is no longer configurable since we're now using features
that are v3 only. Limiting ourselves to v2 compatibility is far too
troublesome and people tend to update to newer versions of PuppetDB
fairly quickly.
