[nielsdrost7]

Description

So when a form is posted it needs to be checked for nastiness. This function (right now in the Admin_Controller) will do that

Motivation and Context

Whenever I post my form, i want to make sure that any nastiness like "onmouseover=alert('XSS') or something" doesn't get through, this function that I added in the Admin_Controller will make an attempt to strip out those things
