- Added service_createGroup function which gives access to group keys and grpItem just before GXS group creation
- Temp fix for GXS services hang on dummy data generation. Given each GXS service own thread and chunked grp creation (separate thread may need to be permanent, no obvious around move grp gen cost away from critical path of tick, but unscientifically increases each services thread tick period to reduce cpu cost) - change grpId assignment from hash of grp data to admin keyid git-svn-id: http://svn.code.sf.net/p/retroshare/code/branches/v0.5-gxs-b1@5772 b45a01b8-16f6-495d-af2f-9b41ad6348cc
