Differentiate between deb-only and git packages

[pazdera]

The list dr list packages should display information about package type (either with or without a source).

All the packages in the output of the above-mentioned command are printed with the same colour. It would be nice to differentiate between the ones that are directly managed by dr and the ones that are only hosted by it (and not built).

What needs to be done

1. Change the colour here based on the package type.
