Validations should only occur on create

As we don't store contact_name etc in the DB, we were getting errors
whenever an update action took place (such as forgetting password,

We certainly don't want the validator key in version control
Ignore all of this stuff
We can fire up a node. Can't quite start the app yet...
OK, WORKSFORME
