Save as Template: Also consider document language

Attempt to save the template in the appropriate language subfolder of
the user template directory (and propose to create it if it doesn't exist
yet).

That way, user-generated templates (1.) get the correct language attribution
in the lyxfiles dialog and (2.) users can easily generate different
language versions of a template.
