Umple 1.30.1 Release candidate
This is a release candidate (pre-release) for Umple 1.30.1
The key thing this does is updates the base docker image to use new versions of php, Java, Nginx, Graphviz, and other software.
There are also some bug fixes and several updates to the user manual.
If all is Good, 1.30.1 will be released on August 7 or 8
