no TLS1.3 with 1.15.5

I am sorry for the late aswer. I never install any compiled packages except for the ones that can be pulled from Ubuntu's official repositories. Since 1.15.5 was not available yet (and the one that was available was compiled against a SSL version which didn't support TLS1.3), I had retrieve the source code for both and do all the hard and fun work myself. :)

Seeing how it works, I believe that it's worth all the trouble.
