Focal point support

Improvements

• Support for centering hero stage and highlight images on focal points defined by editors in PAC has been added.
• When no search criterium has been set, the search view now presents topics in addition to the most searched shows.
• When no subtitles have been explicitly enabled, forced subtitles matching the currently selected audio language are automatically displayed.

Fixes

• Fix incorrect font weight on devices whose language is not English.
