Perform various tasks at the request of the affected WikiProjects:
* Add or remove banners on a specific set of pages (e.g. pages in a category, pages transcluding a template).
* Adjust banner parameters, particularly assessments and task forces.
* Fix banner shells on pages edited for the above reasons.
