www/mediawiki update to 1.5.3 (security update)
Fixes a security issue: Validation of the user language
option was broken by a code change in May 2005, opening the
possibility of remote code execution as this parameter is
used in forming a class name dynamically created with eval().
The validation has been corrected in this version. All
prior 1.5 release and prelease versions are affected; 1.4
and earlier and not affected.
