[winswitch] migrating away from trac and svn

[Antoine Martin]

Hi,

It has become necessary to move the bug tracker and wiki away from trac.
The current plan is to transition to github and gitlab by the end of the
year.

If you have any opinions or suggestions on how / why this should be
done, feel free to respond to this thread or on this ticket:
https://xpra.org/trac/ticket/2967

Thanks,
Antoine
