Allow Forms in HTML Purifier Configuration
I use HTML Purifier to clean input in my CMS.  Many of my clients like to have PayPal donation buttons in their site, but HTML Purifier strips the forms out.  I noticed that HTML Purifier has a `HTMLPurifier_HTMLModule_Forms` class, but I don't know if that does what I want.  If it does, how do I enable it?

Thanks!
