Crap to make the project compile

dropbox + git = headaches
Make tests easier to follow and compare
Test name shown and more pre-bench warmup
Last 2 points necessary to get boxes performance

That's:
1) fixing https://github.com/miniboxing/miniboxing-plugin/issues/63 (sorry @HaprianVlad, but we needed this fixed for the benchmarks)
2) `-optimize`, which should become useless when using the java runtime (will work on this next week)
