- across all files, ship names are now in lowercase unless they describe specific unit types (such as 'Medium Warship').
- spelling errors fixed across all files, even if it means renaming them:
As fatherbushido noted:
*liburnus* - (a man from Liburnia) -> *liburna* - (a Liburnian (ship type))
Following rP16666:
*penteconter* -> *pentekonter*
A longboat is something quite different from a longship:
*longboat* -> *longship*
