The frontend code was still using the legacy RainbowMan, with the wowl
webclient, we rewrote this RainbowMan and started using that one
instead, but because the frontend code had no access to the wowl
environment, the legacy version was still used in the frontend. Since
the frontend now has access to the wowl environment, the old code can be
removed and the calls can go through the new effect service.
