[winswitch] [ANNOUNCE] Xpra 0.17.6 (many fixes)

[Antoine Martin]

Hi,

This update contains a very large number of fixes, including a critical
fix for the NVENC encoder when used with Nvidia's Pascal GPUs: this
prevents hard system lockups (local DoS bug in their drivers).

Other notable fixes: some printing issues, many fixes for OSX and the
proxy server, build fixes. Updating is recommended.
