[Mediawiki-l] blank page after install +patch

[Joshua Swink]

If you install php and mysql for the sole reason of running Mediawiki,
and are inexperienced :-) and forget to uncomment ;extension=mysql.so,
you get a blank page in your browser after running the script in
config/index.php.  Here is a patch to make it painfully clear what
is going wrong in this situation.  It checks for mysql prior to
asking you to fill out that form.
