Updated docuwiki package fixes CVE-2014-9253

Updated dokuwiki package fix a security vulnerability: Our current dokuwiki-20140929-1.1.mga4 package uses dokuwiki-2014-09-29a source which allows swf (application/x-shockwave-flash) uploads by default. This may be used for Cross-site scripting (XSS) attack which enables attackers to inject client-side script into Web pages viewed by other users. (CVE-2014-9253).
