Addition to patterns form helper

I already found a bug. Here's the file. I think this can be committed anytime after some testing.

and another bug I'm working on. It did not deal with valid xhtml, which also needs to be embedded in CDATA tags. It would put bad xml in CDATA, but not good xml.

On the good news side, I used this to export a user settings form successfully. This one is always a customization.

I think I've got this working well. Below is an xml and yaml example of the user settings form. I know I can't import yaml and the filesystem isn't discovering the file. If this looks about right, let me know and I'll post the patch. With the form helper, there is no need to accomodate multidimensional arrays since they aren't present. But after a little work with YAML I can see it will be easy to implement in the other "generate" functions.
