Add support for Event reminders and Newsletters via SMS / Text

Hello –

Currently our Scouts, like many Units, rely on text messaging as reminders to get things done. Event reminder emails tend to go unread. We would like to request that Trooptrack support a per-Unit feature toggle which allows Units to opt into sending reminders via SMS / Text in replacement of or in addition to Email reminders.

We care mostly about the Event reminders, however Newsletter comms would also be great (perhaps optimized for mobile where it is not as verbose?).

This would couple extremely nicely with the Add Twilio and related provider support for SMS / Text messaging feature request.

Thanks!
