Undo an Attendance Mark, and Manage Contact Preferences

Three refinements to the things staff do dozens of times a day.

• Unmark attendance. Tapped the wrong name? Tap it again to clear it.
• Phone numbers are optional on additional contacts — a grandparent with only an email address is still a perfectly good emergency contact.
• Manage email preferences from the record. If a family asks to come off your email list, staff can action it directly from their contact record, and it's respected across your broadcasts.
