fleet names are problematic

[wchristian]

This is a cutout from #14:

Overflow here looks sloppy. Happens in a lot of the windows.
This window is while assigning an Escort Fleet

Other example, same issue, different location.

There is a general issue here: Default fleet names are automatically generated with contextual strings added in, but with the english fragments they tend to be too long and don't fit visually. Additionally when editing them manually they tend to get truncated.

Not critical and purely cosmetic for the moment, but will need research.
