Hamcrest version 3.0-rc

[Joe Schmetzer]

I've just published the first version 3.0 release candidate. The only main user visible change is that is code is compiled to Java 1.8 bytecode (version 2.2 and previous were compiled against Java 1.7). The full list of changes is available at https://github.com/hamcrest/JavaHamcrest/blob/master/CHANGES.md

I'd appreciate it if people could try it out and let me know if there are any issues.

Thanks,
Joe
