[Pharo-project] a process to maintain non core package

Hi in the future I would like to have a process like that to maintain package like sound (or morphic extras) or any package that are not core else we will not be able to maintain them or to apply package wide changes. - we mark the packages that are not in the image but that we want to maintain - at integration step we load all the external packages - integrate - publish in different repos Else I bet that we will not be able to maintain the non core packages. Stef PS: I'm integrating Issue 1051: Cuis 0053-ensure-close.1.cs and some changes touched sound so this is good experiment.
