Subject: WINTERMUTE: Rename CamelCased filenames to
 prefixed_under_score-filenames

This is mostly a lead-up to namespacing the Ad/Base folders, and then
possibly removing the prefixes from the files, it also has the added
benefit of getting rid of the odd case-typos that makes for issues
on platforms that don't ignore case.
