[Gameplay] Complete Naval Overhaul (UnitAI and Warship Classes)

Warships now use the Unit AI instead of the Building AI. This allows players to specifically target fire onto desired targets.
Warship combat now revamped with completely new Warship classes, which soft counter each other, and new behavior for Fire Ships. With an all-new ship tech tree at the Dock.
Commit includes fixing maps to switch from the old to the new ship templates. Also includes revamped Cycladic Archipelago skirmish maps and some other special surprises. And improved/additional ship UI portraits.

New Warship classes:

Scout Ship
Arrow Ship
Ramming Ship
Siege Ship
