Stuff talky needs

This now assumes that *_config.json provides:

```
andyetAuth: {
  id: 'blah'
  secret: 'donttell'
},
andyetAPIs: { // this is for overriding production api urls for localhost variants
  accounts: 'localhost url if not using production'
  shippy: 'ditto',
  talky: 'ditto'
},
bucker: {bucker stuff}
```
