Better setup for impersonating users
Responders page: limit number of response icons, properly sort
Have Person enforce that at least one phone number must be enabled
Reminders#daily_sms_reminder should be graceful if a person has no valid phones
Support simple string arrays in serialized columns
Support per-chapter configuration of resources tracked on dat incident report
Add descriptive titles to incident pages, move some of the lookups to use assignable values in prep for per-chapter config.  Reorder the damage assessment form to maybe make it less confusing.
