M112-T134-A002 Testing return count, implemented with M112-T131-A002

Return value should only be a single value, the number of total results available in DB

M112-T134-A002 Testing skip/offset parameter, implemented with M112-T131-A005

Return should differ when skip/offset parameter used

QueryLanguage had to be modified, was setting 'offset' value, 'skip' is word used by DatastoreQueryLanguage

These tests are still questionable, order_by parameter is not implemented in Datastore, pre-loads 200 values
so there would be a 1/200 chance the first result in non-skip query equals the 100th result if skip query. Need order implemented.
