[winswitch] [ANNOUNCE] Xpra LTS 3.0.13: many fixes, none critical

[Antoine Martin]

Hi,

This update to the LTS 3.x branch brings most of the fixes already
applied earlier to the v4.x branch, and so the release information is
largely the same:
* there is no urgency to update if you were not affected by these issues
* the "~/.xpra" path has been re-added to the list of socket directories
* the PDFium printing library has been updated in the MS Windows builds

Next, the 3.0.x LTS branch will be replaced by the 3.1.x LTS branch.
Whereas previous updates to the 3.0.x branch were almost exclusively bug
fixes, this new 3.1.x LTS branch will also backport some new features:
generally self-contained changes that are very unlikely to cause
regressions.
