When creating a wiki link ((foo))), Tiki uses the target pages's description as the the link's TITLE attribute. It would be nice for external links to also have a TITLE attribute. Tiki could use the link's description, or a generic text. For example:
[http://foo.com|my link] would become:
<a href="http://foo.com" title="External link: my link">.....
[http://foo.com] would become:
<a href="http://foo.com" title="External link">.....
