Add Ship Class Name to Retrofit Window

Description

Currently when you choose Retrofit on a sector with vehicles you get a list of checkboxes for every ship. Next to each checkbox is the ship's name. There is enough room for the ship's class also to show up on the right side of this window. This would be EXTREMELY useful information because normally when you build a ship it uses the ship's class in the default name, but when you retrofit to higher model the name does not update so it appears as if it is the old ship on most of the UI unless you see the class name as well.
