The <SpecificName> and <Actor> values do not belong in the generic templates, they should be in the specific templates in the sub-folders.
This patch:
- removes <Actor> from the generic template_* files
- adds the appropiate actors to their specific children in the cases they were not yet included there
- removes <SpecificName> from the generic template_* files
- adds the appropiate specific names to their specific children in the cases they were not yet included there
- removes <GenericName> from the gaia/ruins/* files
- removes <GenericName> from the gaia/treasure/* files
- removes <Icon> from the gaia/treasure/* files if it's identical to the parent template
<Actor> is still present in the following generic templates:
- template_formation.xml
- template_unit_catafalque.xml
