Title: suggest sync/init to user as appropriate

If I do 'cargo install csv' without having run 'cargo init; cargo sync;' the message used to be just 'No packages.' This suggests the user run cargo init; cargo sync if cargo init has not been run. If there are sources but no known packages, cargo sync is suggested.
