This patch:
- allows the Mauryas to build their palace (limited to one);
- gives the palace the same territory influence as the Persian apadana and tacara;
- replaces the female citizen with the maiden guard champion in the palace training queue;
- removes the maiden guard archer from the Chandragupta hero training queue;
- removes the maiden guard swordwoman from the barracks;
- renames the champion infantry maceman template and removes their unlock_champion_units requirement;
- removes the champions and heroes from the Mauryan fortress training queue.
As a consequence, the Mauryas can immediately train their champions upon advancing to the city phase, but each at a different structure:
- the maiden guards at the palace;
- the maceman at the barracks;
- the chariot at the stable;
- the elephant at the elephant stable.
Basically the Mauryas become a bit more similar to the Persians (who also have a palace for their heroes and an infantry champion) and a bit less similar than the Macedonians (who can train champion infantry at the barracks too, but need the unlock technology, unlike the Mauryas). And since the Mauryas were historically influenced by both the Persians and the Macedonians, having a bit of both in game seems not entirely inappropiate.
