Subject: [PATCH] Add support for package sets to quickpkg

Split quickpkg_atom out of quickpkg_main to handle single atoms.
Create quickpkg_set to handle sets that calls quickpkg_atom.
Use a dict called 'infos' to return information about skipped config files, etc.
Move imports to global scope.
Update --help message and man page.
