**Motivation**
There are some notes in the [[ https://www.mediawiki.org/wiki/Extension:FileImporter/Data | FileImporter config files ]] that made sense for CommonsHelper2, but are unnecessary, and if anything confusing for FileImporter use. They should probably be removed.
At the same time the config files are the place where users would usually go to change the configuration around FileImporter, but for the "Now Commons" templates, this info is actually stored in Wikidata. Thus we should at least add a pointer that the info can be found there.
**Acceptance Criteria**
[] In all existing config files
[] Remove all lines containing the magic words `%AUTHOR%` and `%TRANSFERUSER%` plus their titles
[] This includes, but may not be limited to the `Transfer` section help text, and the `Transfer` section keywords `self`, `self2`, `multilicense replacing placeholder` (see also T198609 in case of more background info need)
[] Use the edit summary !!TODO ask Johanna!!
[] In all existing config files
[] make sure that there were no changes to the Information section
[] delete the information section (in case of need of more background info see T198315)
[] In all existing config files add a new section
[] Title: Source wiki info
[] Help text `In Wikidata you can store which template should be used to signal a file's move to Commons on the Wikipedia version of the file. Please do not add this info here` !!TODO Johanna needs to polish the text!!
[] Wikidata should link to https://www.wikidata.org/wiki/Q5611625
