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
Seems that it was missing a layer -- did this:
```
        transformed.contexts = fluid.transform(prefs.contexts, function (context, contextId) {
            return fluid.transform(context, function (val, key) {
                var rule = gpii.ontologyHandler.contextBlocks[key];
                return rule === null ? val : fluid.invokeGlobalFunction(rule, [val, transformSpec]);
            });
        });
```
