catalog: make translated_title behave more like title regarding %

translated_title is used in listbox search columns, so it's very confusing
for users if they can not use the usual % character for partial matches.

This changes the behaviour of translated_title to autodetect the presence of
% and use LIKE comparison operator in such case.
