feat(authentication): add support for auth0 login using lock
Adds an Auth0Lock provider class that wraps the Auth0-Lock library. It activates when the oauthType property is equal to 'auth0-lock', and expects some peculiar properties in its configuration block (see the sample config in baseConfig.js). TODO: proper testing; better way to load it (provider extensibility api)
