Title: Field help text escaping change

I had a need to use HTML in the field description help parameter. It was escaped by default so I have added `|raw` to prevent it removing the HTML. I can't see this causing a security risk unless you are populating the help parameter with user input - a reasonably rare scenario I imagine. This gives you far more flexibility, for instance, I needed a line break.
