* Fixes bug in v1.6.0 with the return reponse (for those extending NextAuth), it was returning an empty response after refactoring.
* The instance of Express is now returned in ‘expressApp’, the value ‘express’ now contains Express library being referenced (making it easier to use it for things like creating static routes).
* Removed depdancy for cookie parser (resolves#15).
* Example now uses Next.js 5.0.
* Pruned unused dependancies.
* Fixed missing depdendancies for example project.
* Resolved issue with missing dependancies for building the client lib.
* Now trust proxies running in front when they say they are running the site over SSL (e.g. Heroku, nginx, AWS, etc).
* Now uses secure cookies on HTTPS enabled sites.
The oAuth profile for a service is now passed to update() and insert() when signing in via oAuth (or linking accounts).
e.g. `update(user, oAuthProfile)` and `insert(user, oAuthProfile)`
This provides a way to also capture oAuth provider specific fields, such as avatar, location, organisation, etc. as needed.
Thanks to @gielcobben for raising this.
