Subject: Do not download Packages/Sources files on I-M-S hit of the Release file

Do not download Packages/Sources files on I-M-S hit of the Release file

With this branch we know that the data in the lists directory is always
what the release file says, so if the Release file is unchanged, then
there is no need to queue the download of the other indexfiles as they
will be unchanged too (or broken :)
