Co-authored by: kevinoconnor7, ohmybahgosh

* Support direct `/player/` URL
* Treat the different versions of an episode as different formats of a single video. So `experience_id` can no longer be used as the video `id` and the `episode_id` is used instead. This means that all existing archives will break
* Extractor options `language` and `version` to pre-select them
* Compat option `seperate-video-versions` to fall back to old behavior (including using the old video IDs)

Closes #428

1. Allow removal of login hint - extractors can set their own login hint as part of `msg`
