Moved /templates/other/special_catafalque.xml to /templates/template_unit_catafalque.xml
and moved templates/other/catafalque/{civ}_catafalque.xml to templates/units/{civ}_catafalque.xml
After all, catafalques are units, and heroes are also in the units/ folder.
It seems (grep) catafalque path location names are not hardcoded anywhere else in simulation/data/ nor ai/ nor elsewhere, nor in any specific maps.
