Preventing MySQL start script from throwing extraneous errors

Having just `test -s ...` was returning `1`, which `set -e` was

Not pulling when pushing

We pull when we build to ensure that we have what's on there, but if we
pull before pushing, and there's already an image tagged with latest, it
will override our current tag
Fixing a few additional things

The `init.done` file needs to be put somewhere that persists between
container runs.  The `env` file needs to be somewhere that's externally
accessible, and we need to trap both `INT` and `TERM` for nice exiting.
We need to delete `.latest_tagged` if we can tag again
