Make address (and other) info validation visible to members

[WillNilges]

We do some validation/correction to peoples' info when they submit the join form right now. That isn't visible to them, so it might be wrong, and neither them nor us would know.

We should confirm with the member before "final" submission to ensure that their information is accurate.

Thoughts: Keep it simple, stupid. Do the bare minimum validation on the client (making sure the form isn't empty) and then centralizing as much of the validation as possible in one place (MeshDB) will be good for us.

Only exception is if we need the client's IP address to get around that one API that rate limits us. (Which API was that again?)
