WIP: Tidy up the forum sync
Add the .env file to be ignored

The .env file specifies environment variables that foreman will set when
its contents for me include
  RACK_ENV=development
  PORT=3000

The TWILIO envvars could go there too, but that's playing with fire. I
don't want people to accidentally receive text messages from me.

Death to utc_offset

Rails is actually decent at handling time zones, provided the stuff
stored in the database is stored in UTC. To do that, the key line is
setting the Time.zone somewhere before anything happens on the page.
Move all times in the database forward four hours

Since they were inputted into the database in UTC-4, this resets them to
normal.
