#333 #326 Refactor protocol recordTypes

[diehuxx]

Another step in the refactor outlined in #326. Also, fully addresses feature #333.

Changes

#326

• Change property label to recordDefinitions. Make recordDefinitions an array, where each element has id, schema, and dataFormats

#333

• Makes schema optional in protocol auth'd RecordsWrites. (schema was previously required for protocol RecordsWrites.)

Other

• Remove duplicate tests and flesh out tests for ProtocolAuthrorization.getRuleSet, particularly testing for new error code DwnErrorCode.ProtocolAuthorizationMissingRuleSet.
