Rename SHF into corvette

[Cap.Kennedy]

Giving it a new name is not a bad idea, as said above Korvette is in employ already though.

Regardless, there's a wide selection of alternatives you can pick from: http://en.wikipedia.org/wiki/Category:Ship_classes

Well apart from civilian ships and submarines as much as i can see only ships not covered are Frigates Corvettes and Carriers, although later two have single representative each it can hardly be called a class.
