* Remove some creation dates, they are not protected by GPL
* Remove duplicate @defgroup API
* Remove @ingroup from some @file doc comments on class files. It is not
useful to list class files alongside classes in the doxygen module menu.
Add @ingroup to some more class files that had @ingroup on their file,
that was probably the author's intent.
* In PackedOverlayImageGallery, use the file comment as a class comment
* Don't put @defgroup and @file in the same comment. @defgroup makes the
whole doc comment describe the group.
* Instead of putting AnsiTermColorer in two groups, use hierarchical
groups.

Xenon shows a significant amount of time is spent individually fetching
the content model for titles being purged. It's probably not a huge
improvement but lets fetch them all in one go instead of lazily as
needed.
