Make nickname a required meta field

Add missing nicknames
Use SPDX ID if no customary nickname (eg GNU GPLv3) exists

This ensures that a relatively compact name is always available

I may be missing some obvious customary names, e.g., is "Eclipse
1.0" customary? For now I've used the SPDX ID, EPL-1.0.
