This patch changes the name of the Apadana special building to the Tachara. It's what the special building's model was modeled after anyway. T
The name "Apadana" will eventually be used for the Persian Wonder: https://wildfiregames.com/forum/topic/17552-task-wonder-persians-apadana-of-darius/
The patch changes the actor of the Tachara to the more interesting civic center model and the civic center's actor to the old "tacara" model. The new civic center model will be improved in the near future to something along these lines: https://i.imgur.com/3Lfptos.png
The patch also makes sure the name change is good for the builder mixin and the AI. If I missed anything, let me know!
