Bug in references URLs

In some references to internal resources, sioc.module uses $base_url."path" to define linked resources (w/ rdfs:seeAlso).

Yet, some drupal websites use http://mydrupal/?q=/node/id URL syntax instead of http://mydrupal/node/id, depending on their configuration.

So you had better to use url("path", [params]) anytime, so that there won't be broken links in references.
