As elexis discussed with Sandarac in irc, me and Grugnas in the lobby, proposed in #4518, D152 and rP19345,
we should have civ specific catafalque templates. This allows
(1) We can name a great leader that remains in each catafalque spawned
(2) Those catafalques become unique, even if multiple of them exist on a map
(3) Each of these relics can receive a slight bonus, similar to heroes, for example auras or resource trickle
The units therefore become more interesting to collect , even if not owning all of them
(4) Allows specification of civ specific visual actors
