Open source build

As a result of Nanobuilder becoming open-sourced and uploaded to my portfolio, I've built some binaries so people can try out what Nanobuilder is about, without going through all the faff that is installing Processing, its Java libraries and then exporting or running from there.

The 64-bit version is bundled with 64-bit Java to make running it easy.

Make sure to select the correct version for you, whether you have a 32-bit processor or 64-bit one.
