 Most files in wordpress/wp-admin/*.php start with 15-lines-code to reset
 vars in an array. So, just move this code to new function and put it in
 admin-functions.php. This is better than write same code in +10 files.

 In the patch i used $_REQUEST because it contain both of $_POST and $_GET,
 this will offer some lines. Also, the var unseted according to #2595.

 Also, isn't "foreach" better than "for"? or at least more cleaner?
