Currently the Mauryan elephant archer has template_cavalry_ranged_archer.xml as its parent, but changes many stats, including removing the Cavalry class.
This is problematic, as tweaking one (e.g. D2585) would affect the other (D2575), something that's easily overlooked.
This patch therefore introduces separate elephant templates, so horse and elephant archers no longer depent on each other, making things easier for balancing, mods, and future additions.
[EDIT] Further changes:
- included footprint changes from D2496
- made it more similar to template_unit_champion_elephant.xml:
- removed slaughter attack
- removed wedge formation
- gave it the same sound groups
- increased vision range to 100
