Set red asterisk on field labels only if it is marked required

Before this, fields had a red asterisk even if they were not
marked with a 'required': true property declaration. This
was confusing for both organizers (who were wondering why this
field was left empty) and for users (who were wondering why this
was marked required, but not really)

Set page title to parsed title of the Campaign

If no title is set it'll just use the campaign name
