Added first iteration of adding movies.

Currently working:
- Searching for new Movies on IMDb (very hacky)
- Adding movie as a series with one season and episode (very hacky)
- Rarbg.to indexer. (somewhat hacky)

TODO:
- Tweak release specifications so that they do not cause exceptions.
- Add Movie struct so that searching for ones is not so hacky.
- rework movies UI.
