Subject: [PATCH] Add option to have a prefix for a taxonomy

As seen in #2449, it might be nice to not serve the taxonomies in the
top level directory, but in a subfolder. This commit adds an option
"prefix" to the taxonomy definition.

The taxonomy then would be served in /<prefix>/<taxonomy_name> instead of
/<taxonomy>.
