Mandatory checkboxes should be marked as mandatory on talk submission form

[Nakaner]

Expected Behavior

If a mandatory question (a checkbox in this case) is not answered, a click on the "next" button in the talk submission form should either show an error message or highlight the question to be answered (e.g. red font colour, bold font or different background colour)

Current Behavior

If a mandatory question (a checkbox in this case) is not answered and the user hits the the "next" button, nothing happens.

This bug has been reported by another user and I can reproduce it.

Steps to Reproduce

1. Add a mandatory checkbox to the CfP form.
2. go to talk submission
3. complete the first page of the form and click next
4. don't check the mandatory checkbox on the page "Erzähl uns mehr" (/CONFERENCE_NAME/submit/TOKEN/questions/)
5. click on "next" … nothing happens

Your Environment

does not matter
