- 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)
I chose what Wikipedia preferred when spelling was inconsistent:
*pentekonter* -> *penteconter*
A longboat is something quite different from a longship:
*longboat* -> *longship*
