Update TDEL10n module

Browse Source 
+ Use excludes also on files for extracting attributes.
+ Add ability to extract multiple attributes for one source_spec.
+ Add function to prepare attributes from XML files for xgettext.
+ Use tde_l10n_prepare_xmlattr function instead of extractattr script.
+ Handle working files for multiple extractions from the same source file.
