improvement: querying /packages will also fill all package objects with entries

through the updated api, /packages doesn't provide id-based entries anymore. instead, we now get a package in every line with multiple entries in the versions field, which contains both a version and id information. the package[id] hash is now filled based on this information, while the packages hash contains all packages (instead of all package-version entries like before).
