Block some bw-dev commands from being run in prod

Right now, commands that should not be run in production are removed
from the bw-dev file in the `production` branch. Since eventually I'd
like to get rid of that branch, this change would use the `DEBUG`
environment variable to determine if a command should be disabled,
rather than depending on the file available in the branch.
