* Call it "Changes" when referring to the global list of changes (pool changes, artist changes, etc).
* Call it "History" when referring to the history of a single item (pool history, artist history, etc).
* Put the artist history search form on the /artist_versions page, and remove the /artist_versions/search endpoint.
* Remove the /comment/search page. Instead put the comment search form
on the same page as the search results, so you don't have to go back
and forth to update your search.
* Add an "Edited?" search option, for finding comments that have been edited.
* Add options for sorting by oldest comments and lowest scoring comments.
* Fix inconsistencies in how wiki pages were linked.
* Link directly to the wiki instead of to a title search that is expected
to redirect to the wiki.
