Merge of branch v0.6-rssocialnet 7419 to 7488. Changes from electron and myself:

- added possibility to modify groups (e.g. edit circles)
- fixed mismatched free/delete in fimonitor.cc, authssl.cc, pqibin.cc (saving encrypted hash cache file)
- improved plugin interface class to allow plugins to access GXS objects.
- added method to un-register notify clients from RsNotify
- fixed pqisslproxy for windows, due to win not properly supporting sockets in non blocking mode.
- removed static members form RsInitConfig and made RsAccounts object a pointer. This prevents plugin initialisation problems at symbol resolving time.
- removed bool return from p3IdService::getOwnIds()
