#73 404 not returned for missing templates

[W. Jeffrey Rankin]

I've noticed on version 3.5.1 and the CVS version that
requests for missing templates no longer return a 404
status, they return a 200 status. The not found
template is displayed properly, and the request is
recorded on the status > not found page, but the logs
indicate a 200 status. I'm seeing this issue on Solaris
and Windows Server 2003/XP.
