This patch:
- enables the cavalry stables, elephant stables, and siege workshops for all factions that have them.
- removes elephants, siege weapons, and siege technologies from all fortresses
- updated fortress tooltips
- assigned fortresses a territory root, which means that if you lose your centre, you'll still remain in control of your fortresses and keep the connected structures. This means fortresses will be quite useful for all factions, including those who can not train anything at it (e.g. Sparta).
