Update oauth2 client

Maintenance release

Fixes changes to the base package API

The underlying package API changed, merged pulls from @ThePooN to fix issues.

Kraken API required update

Since August 8th, 2016 Kraken API requires a Client-ID header to be sent on any request.

Significant Client Improvements

Thanks to @0plus1 for the excellent pull. Included in the fixes are improved documentation, exception handling and a variety of other fixes.

This also removes Laravel integration, so if you were relying on that, be cautious in the upgrade.

Twitch Logo
