fix #3392 - Removes html and css for original form

[karlcow]

This PR fixes issue #3392

Proposed PR background

We switch to the wizard form. This PR removes the HTML and CSS code related to the previous form

I hope I didn't miss anything.

Just a drive by comment, the wizard styles actually depend on css in the form.css. I think also some other form elements across the site using it. So some of the code should stay.

I've started refactoring it, but got carried away by the fixes for IE11. So if you like, I can do the css part @karlcow

(It sounds like maybe we should not merge this PR yet)

Ah cool! I tested yesterday and didn't see any failures, but I was not sure, it's why I was asking for review.
