Online Contribution - Honoree section allows you to select in honor off without entering honoree information and doesn't include an unselect

If the honoree section is included in online contribution pages, the form validation is problematic. You can select 'In Honor of' or 'In Memory of' w/o putting in an name or email address. The result is that no honoree is created / linked to the contribution - but the user gets no feedback on this.

Modify formRule to require either first and last name OR email if one of the In Honor of radio buttons is selected. Also add an 'unselect' link in case folks decide not to do 'In honor of'.

Also changed the field layout to be more compact and easier to read.
