New version with minor improvements
+ move sets of services to different date/time - handy thing I needed
+ program handles well opening of associated data files (after clicking data file it is also opened) - reported bug that file associations did not work well
+ sample of XML output customization that produces formatted HTML table - one user needed to produce customized output for WordPress - script in customization/lipuvka.rb does that
+ Delete key deletes the calendar entry
+ migration to recent version of user interface toolkit Qt 5.4.1
