Add new property filename, because URL and filename does not store same values.

DMS was storing filename value in source_reference property, this will change, filename
will be used explicitely.

Warning: For consistency all variables or methods with id file_name or FileName
will be deprecated.
Methods will only receive filename as named argument and Filename as token in method name.
 - getPropertyDictFromFilename
 - getStandardFilename
 - ...
