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 :)
