GPII-784: Framework is now supporting the new NP set format

GPII-784: Updated all the NP sets, tests, etc. to use the the NP format. The MM has been hardcoded to pass on the "gpii-default" context to the rest of the framework until we implement the context manager, etc.
GPII-939: Updated the grunt script to json lint the testData folder as well
sure! Looking through the code, I see it in quite a few places -- should I just go ahead and fix it everywhere? (wouldn't be a problem)
