This commit removes all legacy utils except Markup, which will be
removed in another PR. A lot of those utils were no longer used and
thus have just been removed. Those that were still used either
already existed in the wowl codebase, so usecases have been adapted
to use the new version instead. A few have been re-implemented (or
moved basically) to the wowl codebase (e.g. isEmail and humanSize).
