This patch is similar to several earlier patches:
* D1036/rP20682 separated champion maceman template.
* D1354/rP24478 introduced maceman templates.
* D1355/rP23780 introduced axeman templates.
* D2595/rP24212 separated elephant archer from cavalry templates.
This patch introduces crossbowman templates. Currently there is only in game, `mace_champion_infantry_crossbowman.xml`, but future additions are not inconceivable, and having the templates ready also removes the need to define them in individual mods (e.g. Han China).
