This one's based on purl-go branch, I'll rebase when the other one is merged.

My code for the java and python PURL generation is ready.
I'll give a PR after this is merged.
Next I think I'll be working on ruby, swift and perl @terriko

Re-running the failing windows test. I'm not actually sure how this could possibly have caused the failure it's having.

[inosmeet]

Seems it was due to bad cache.

Been a while but I think we're good to merge. Thanks for your patience!
