(Update) blutopia.yml (#3357)

- added new input field "description" which is used to be able to search into torrent descriptions and media info using keywords
- This doesn't fix #3355 . Im not sure what the issue is. Maybe @kaso17 can check it out. I believe you still have a account there. If not let me know.
