Docker things I noticed trying to run my own dat registry

[SvenDowideit]

so this has a bunch of things:

1. I removed port 25, as that implies datBase is an SMTP server - if its only sending emails, it shouldn't need to listen to port 25
2. I re-used some of the ENV vars so constants are only set once
3. added the defaul.js config, so the image on the hub can "work" - and then users would customise it.
4. moved nodemon to the prod dependencies - closes #627
5. added a docker-swarm-yml, which should go some way to showing how you could run datBase in production.

however, it doesn't work - i can't run dat register or dat login against it - both fail with cannot POST to /register (or /publish/login) I can register a new user via the web UI.

I presume I need to set something else up?

I also get

mmm, or another failure trying to register (with nothing in the container log output):

The resulting web site is obviously the datbase.org one - so I'll need to customise - but at this point, I really just want to get started..
