Add production group without -Tests and -Examples packages

[tinchodias]

This helps to create the explicit package lists:

all :=(BaselineOfBloc new project version spec packageSpecsInLoadOrder
	select: [ :e | e class = MetacelloPackageSpec ]
	thenCollect: #name).

dev := all asArray asString.
	
prod := (all reject: [ :e | (e endsWith: 'Tests') or:[e endsWith: 'Examples'] ]) asArray asString.
