get in sync with HEAD again
-OPimBase was added to be used as a default struct inside OPimResolver and to work with DSOs -TodoListXML backend now uses mmap and madvise to load data -OContact added/changed rtti -OTodo added changed rtti OPimAccess* added stuff necessary for the Resolver and a 'state'/'hint' on how to load data OPimResolver which resolves uid + services to Records, rtti to QCOPChannels loads arbitary Service backends ( will work with DSOs soon ) -OPimMainWindow added some setDocument scripting possibility and internal marshalling and demarshalling of Records -OPimRecord added loadDataFromm and saveDataTo for marshalling purposes much more :)
