This project should move to github/gitlab

[Paul Cercueil]

Hi,

Sending patches via email works, if there is someone on the other end 
applying them, which does not seem to be the case for that project 
anymore. I gave up trying to upstream some patches after 3 attempts 
without feedback, and I'm not the only one in this case, it seems.

I don't blame the maintainer, who may have very little time on his/her 
hands, but this situation will eventually lead to the death of the 
project, if those who want to contribute don't have the means to do so.

So let's move the project to github/gitlab, which will allow PRs to be 
*visible* and not buried in a mountain of emails, and bug reports to 
actually be seen.

Last but not least... Improving Lightning right now is a real pain, 
because truth to be told, nobody will run the tests on all archs after 
each commit. But a CI instance on github/gitlab can totally do that. 
Creating a PR would trigger the tests on all supported archs, and we 
would immediately detect when something has gone wrong.

Hopefully you will agree that it makes sense and is a step in the right 
direction.

Cheers,
-Paul
