Mediawiki: Fix invalid XHTML ouput generated by includes/EditPage.php

PROBLEM

        Invalid markup is created when previewing a page, e.g:

        <p><center><font color="#cc0000"><strong>Note:</strong> Remember that this is only a preview, 
        and has not yet been saved!</font></center></p>

        The XHTML specification does not allow <center> to occur inside of <p>.

SOLUTION

        Replace <p><center><font color="#cc0000"> with 
        <p style="text-align: center; color:#cc0000;">.
        
APPLY THE PATCH

        cd mediawiki-1.4.x/
        wget http://rbach.priv.at/Patches/mediawiki-20050715.diff
        patch -p0 < mediawiki-20050715.diff

	"Bug 2870 - PATCH: Fix invalid XHTML ouput generated 
	by includes/EditPage.php"

	It was marked as "SOLVED" but the patch was not
	applied to the code because of the following reason:
	> Comment #1 From JeLuF 2005-07-16 21:24 UTC
	> This is already fixed in MediaWiki 1.5. 
	> The layout of that paragraph has been
	> moved to CSS.

	Unfortunatly at the time of this writting MediaWiki 1.5
	is still a beta release.
