Implementing required validation on forms on frontend

Implemented using the innovations form. Doesn't seem like others are implemented.
Should work for every form.
```
        q.parent().find(".errors-container").first().append("<li>Emails don't match.</li>")
        q.parent().addClass("question-has-errors")

        validates = false
```
We also do this a lot, we should try to dry it up, since it's making this really long.
