Pulling the user visible part of last checkin

I see other bugs coming in from Scratch and I figure I should work more
volunteer stuff in a branch to save mainline for more bug fixes.

The volunteer coordination stuff checked in so far should be both
functional as is, and only visible to Admins.  HOWEVER - pushing
yesterday’s checkins requires a DB update (1 column added to
scheduler.Events).

Should talk on Thurs on when to push (probably this weekend?) so that
we can get any production fixes out there.
