Gender game: highlights should depend on language

[Waldir Pimenta]

Currently all pronouns are highlighted regardless of the text language. The Spanish "la" for instance, appears often in French but with a different meaning (i.e. it doesn't provide information about the gender of the subject) -- I've even seen it being highlighted in a Chinese article that happened to contain the title of a French work!

The pronouns to be highlighted should depend on the language of the article being displayed.
