CMP's fail when namespace contains slashes

[fireproofsocks]

If you create a namespace such as "vendorname/packagename", the modmanagercontroller.class.php file, the modExtraManagerController class, getControllerClassName() function fails to generate a valid classname so it's impossible to use the recommended MODx rules for CMPs and manager controllers.

The classname needs a regex that filters out invalid classnames:

return ucfirst($namespace).implode('',$o).$postFix;
