Add a "meta" field for the Package struct

This field may be used by the packager to define meta information on a package
and later use that meta-information in their packaging scripts. For example:

    meta.description = "A simple package"

and later use that to write a RPM spec file:

    echo "Description: {{this.meta.description}}" >> specfile
