- modified rsphoto/p3PhotoService interface to conform to 'developing style'
- shifted fakeprocessrequests() to p3GxsService - as its generic.
- added requestMsgRelatedList() request to allow searching for OrigMsgId, MsgVersions + LatestVersions.
- added RsTokReqOptions class to allow fine tuning of requests.
- major changes to p3WikiService to conform to new standard.
