* Machine Driver fixes
- Github activate must set setting on userStore
- Custom driver doesn't really need to extend driver
- Fix custom driver when new registrationToken needs to be created
- Add Machine driver needs to use userStore
- Wait for custom driver UI JS/CSS in beforeModel so custom UIs can load consistently
- CSP rules localhost:3000 custom UI host
* Show UI URL on drivers
* Use isRancher instead of isPrivateLabel
`{{#if settings.isRancher}}` will fail-safely if you forget to include
`settings.` or the injection or type something wrong, rather than
`{{#unless settings.isPrivateLabel}}` failing and showing Rancher stuff.
* Load UI and CSS through proxy if not local
* Remove unused helpers
