Removed “town phase” in brit and gaul blacksmiths; this relict is both unnecessary (it's already defined in the generic blacksmith template) and potentially problematic (if the blacksmith would be changed to a different phase, brit and gaul blacksmiths would still be town phase); for comparison, none of the other civ blacksmiths has these lines of code.
Also added “town phase” in maur elephant archer, to prevent maur from training them in village phase if they somehow acquire (e.g. capture or start with) an elephant stables.
Update:
Also added a “town phase” requirement to the healer.
Added a “town phase” requirement to Carthaginian infantry mercenaries.
Removed unnecessary “city phase” requirement from maur and sele champion war elephants and mace champion pikemen; no other champions had this.
maur_hero_chanakya is the only hero with a “city phase” requirement (unchanged); this is necessary, because it's not based on a hero template, but instead on the basic unit template.
Cavalry has “town phase” requirement by default, javelin cavalry “village phase”; this leaves just six exceptions (mace, ptol, rome), far more efficient.
Furthermore, removed “town phase” from gates and “city phase” from champion skirmisher cavalry.
