Java 8 Rebased on 2.6.1

Contains Java 8 emulation and magic-method-injection support. Lots of emulation, including java.util.function, default methods on collections and most of the reflection classes. Reflection itself is not implemented on this release, however, it will be made available if there is interest in testing it out. Some JsInterop is included, however, it is not really tested.

This release is entirely experimental, and is provided to give early access to java 8 features. Please report any bugs you find via issues on github so they can be fixed before this code gets into master.

Thanks.
