- Rename the "Medium Warship" to "War Barge" since "War Ship" isn't a too common name and for consistency with the loading screentooltip as proposed by fatherbushido
- Remove template duplication by introducing a new parent template for the "War Barge" inheriting the "Trireme" template:
The "Medium Warship" available to Mauryans, Gauls, Britons and Iberians inherits the trireme template.
But since it is the logically an own class, some values are duplicated to each of the "trireme" templates of that civ, f.e. Max Health, Max Garrison, WalkSpeed and Name.
It is easy to not keep them in sync, for example rP18402 removed an unexplained drastic mauryan ship health bonus from rP12007.
- Remove template duplication by letting the "Trireme" template inherit the "Bireme" template.
