Subtitle extraction for tvshow

We now extract subtitle for TVshow in the download screen.
Bookmarks settings (WIP)

- Added bookmark view (favorites)
- Added local DB
- Added system to show tvshow/movie in same list

TODO: Give some love =)
Update movie_item
Fix the filterbar not re-apearing after watching a movie/Tvshow
Click on cover

TODO: Play with z-index because actually if we click on add to
favorite, it trigger the show detail. (also with a preventDefault)
Remove queue

We’ll NOT push 0.3 with Queue system (it’ll be for next releases)
