Stable release 1.3.0

It has been 3 YEARS since we last offered a stable release and the
list of changes is gigantic. The detailed commit list is here:

This release is stable, but not perfect. There are known issues documented
at Github. It is however light years ahead of the last stable release and
even with known issues far more stable and superior in just about every way.

Many thanks to everyone supporting the project in any way they can.
Special thanks to the Tiki Wiki team for all the incredible help they
have provided (https://tiki.org/). This will be the first of a more regular
release schedule, at least more regular than every 3 years!
