Lumping facilities / units / cargo

Description

For the sake of better easier handling and saving time, units really need to be lumped together in groups. Say, all undamaged units would be displayed as one entity with a number and could be scrapped with two clicks (one to scrap the group, and a second to confirm the scrap amount, which ought to be defaulted to the number of the group). Currently, scrapping fighters and units (to save on maintenance costs) is a chore, having to select each and every one individually. The same could be applied to facilities, I suppose, as they are displayed in the same screen to scrap units.
