Title: getExtSourceAttributes moved to getExtSourceById

- getExtSourceAttributes erased and all its functionality is now in
getExtSourceById
- added new mapper for attributes from table ext_sources_attributes
- setAttribute method added into ExtSource object
- methods getExtSourceByName, getVoExtSources, getExtSource no longer
call getExtSourceById.
