[gnome-software/wip/rancell/apt] Allow free-but-unspecified SPDX tokens

[Iain Lane <iainl src gnome org>]

commit fb42d4b78f437ba75873de037b19b96b2f2b7285
Author: Richard Hughes <richard hughsie com>
Date:   Thu Apr 7 14:23:48 2016 +0100

    Allow free-but-unspecified SPDX tokens
    
    We also allow custom URLs for tags, for example:
    @LicenseRef-free=http://www.ubuntu.com/about/about-ubuntu/licensing
    
    Based on a patch by Robert Ancell, many thanks.
