Beta Release v3.0.0-beta.1

This beta update mainly addresses the need for compatibility in projects that already require v1.9.x of the dependency AsyncHttpClient (#75) – thanks to all who participated in the discussion and @dkharrat for PR #76 which finally landed.

Note that moving forward, JDK 1.6 compatibility is dropped. If you were running on JDK 1.6, you should start migrating your application and systems to a later version, preferably the latest (1.8). This constitutes a potentially breaking change, hence the project has bumped the major version number. At this time, there are no plans to backport future changes to v2.x.

Other minor updates include updating the client side of the HelloWorld example (#83), and removing the docs directory from the repository (#88).
