Could/should taxonomies work with `|link` filter?

[I-Valchev]

Currently each taxonomy has a link property, e.g. it can be accesses by using {{ taxonomy.link }}.

The record link, however, is {{ record|link }} which is very much the intended behaviour.

But, for consistency and simplicity, should we make the link filter accept a taxonomy as well, e.g. {{ taxonomy|link }}
