This is a continuation of #6083, which only deals with the long deprecated option to specify individual material properties in the parameter 'Postprocess/Visualization/List of output variables'. This has long been replaced by the visualization postprocessor 'material properties', but we never consistently updated all parameter files in the repository. I changed the update script to automatically replace the deprecated options with the 'new' postprocessor, applied the update script to all prm files in the repo, and removed the legacy functionality in the code to automatically replace those options with the new postprocessor. Now an assert is thrown if users still use the old option, the assert also explains how to fix this. In a few years we can then remove the assert.
