[Card] Add a setting for the language used in card search

Localized card names and texts can now be searched too, controlled by a
'Language used in card search' toggle (English, selected card language, or
both) on the general settings page. Untranslated cards always keep matching
in English.

Removed the redundant local copy of the URL templates list in the localized
picture loader while here.
