As per request, I have patched SpecialUpload.php (unstable branch) to
request copyright status and source upon upload (in place at the test site).
This requires
$wgUseCopyrightUpload = true ;
in LocalSettings.php
Also, changes to wfRecordUpload in GlobalFunctions.php were necessary,
and two lines in Language.php.
Should be in the CVS now.
