Add write support for Fgdb layers and make it possible to remove a prefix from the expressions. The expressions returned by arcgis for Fgdb data contain the data source name as a prefix. Mapserver does not need it and does not match those expressions so they have to be removed

<?PHP
switch ($_SERVER["HTTP_HOST"]) {
 case "www.mxd2map.org":

   $target = "index-de.html";
   break;

readfile($target);
