Wip/h3nk3 play specific plugin

Unfortunately the functionality in this PR still requires two set of keys (NewRelic and NewRelicPlay) for the settings to work. Haven't figured out why but I thought I'd create a PR of this as it works albeit requires a somewhat overly complex configuration file for Activator to work as intended. This can be solved going forward.

Review by @havocp and/or @corruptmemory por favor.
Still needed?
