[ANNOUNCE] wayland 1.15.91

[Derek Foreman]

This is the alpha for wayland 1.16.

It's not so large as the weston release, but still some notable changes
here:
The client definition of wl_global is removed - this really shouldn't
hurt anyone since it's been deprecated for a very long time.

Some long standing oddness has been fixed with destroy signals - this
should only be noticed in cases that were previously problematic.

The code generator now supports referencing foreign enums.

And let's not forget we're now hosted on gitlab and have CI. :)
(and the new contributing documentation is worth a read)

It may take a few minutes for the download URLs to work for both of
these releases.
