Currently different civs use different actor file names to refer to the same tower structure, which is inconsistent and confusing. This patch standardizes the file names:
- wooden_tower, outpost_stone, sentry_tower → tower_small
- fndn_wooden_tower → fndn_tower_small
- scout_tower, defense_tower_stone, defense_tower → tower_large
- fndn_defense_tower → fndn_tower_large
- babylonian_tower → tower_babylonian
This is follows the same naming scheme as used by the recently added towers:
tower_artillery tower_bolt tower_double
and by the wall segments:
wall_gate wall_long wall_medium wall_short wall_tower

Not done: remove unused kushites/defense_tower_wood.xml actor, which looks like the generic palisade fort.
