Display outdated information for packages in Debian/NEW

When a crate is already packaged for Debian but is outdated, provide
more information about this discrepancy.

* Include "outdated" in the Debian information
* Color the crate name as yellow, rather than green, since the package
  can't be used as is
* Color the version as red
