Pending removal from the calendar modules (ref #13).

Added java.awt.headless to PlantUML invocation ...

Setting this to true suppresses the Dock icon when running PlantUML
from the shell on macOS.

This seems to work more consistently with include files.
It also removes the need to rename LaTeX output files.

Updated README to match last update.

Automated calculation of current year and first Monday. ...

This means we no longer have to change the dates every year! Note that this does imply that the scripts now always generate output for the current year, so you can’t run them ahead of time (e.g., in December).

Whoops, missed the local configuration input file.

Added jar to configuration.

Added javac to configuration.
