- Gradle build system update.

- Baselining at Java 8.
- Documentation updates.
- Initial Bintray OSS release (awaiting Bintray request approval).

I think we'll need to create an issue to split the core `README.md` file into smaller feature specific files. This should also allow the documentation to be compatible with gitbooks.

I'll add more details to that issue later. Thanks.
