[winswitch] [ANNOUNCE] Xpra 1.0.13 LTS: many minor fixes

[Antoine Martin]

Hi,

This update to the LTS branch catches up with the fixes already applied
to the newer branches.

Updating is recommended for those stuck on this branch.

As mentioned previously, the MS Windows and MacOS builds should only be
used on systems that cannot run newer versions (ie: Windows XP).
The libraries are out of date and insecure and those builds are quickly
becoming unmaintainable. ie: this version drops support for h264 video
decoding on MS Windows.


Release notes:
* fix server crash with application setting invalid X11 atoms
* fix missing windows with some mono applications (ignore invalid atoms)
* fix small X11 memory leak

* fix man page typos
* fix RPM license information
* fix proxy-video-encoders=all substitution (generally not to be used)
* fix handling of tray geometry and keyboard detection failures
* fix connection errors causing the client launcher to exit
* fix spurious error messages caused by video pipeline changes
