• [x] Add clear all button.
• [x] Add to popular shows screen.
• [ ] Maybe move language selector into filter dialog.
• [x] Optimize and test UI (e.g. add labels or title?).
• [x] Ship and use stable tmdb-java.
• [x] Think about database changes to support movies (may be a different provider list, so maybe boolean column to indicate movie support, but what about updating removing show only ones?).
