Motivation
When a file is moved to Commons, its info is likely to need change, e.g. adapting templates. Ideally the editing should be done in the same way it is done when editing a file info normally.

Task
Investigate if we can let users use the new wikitext editor for their editing. The differences to a usual wikitext editing page are:

• There is no discussion page / version history / star ... link in the tab bar above.
• The save button is not called "save", but something along the lines of "use for import"
• When clicking on "use for import", none of the usual save behavior should be triggered. Instead, the new info should be displayed on the SpecialPage of the file importer which shows a preview of what will be imported
