remove patchworks.

[ng0]

We have 22 pages of "open" patches. But they are not really open. I
believe almost no one uses patchworks. I did for some time, and so did
Ludovic and probably 3 more people but that's it.

When I reported some bug to patchworks upstream I was told this is
known and someone worked on it about 9 months ago but never really
finished it and was asked if I want to work on it.
Do we really use patchworks? I don't think so.
Oh look, I discovered another feature/bug: You can only have 1 address
associated with 1 person.

We have been discussing about alternatives, and that's the reason why I
started to package dependency graphs of gogs, kallithea, gitlab and
other version control packages.


Your thoughts?
