[Moin-user] select language

[Tomasz Grobelny]

How do I force moinmoin to use selected language? I set both default_lang = 
'pl' in config file and appropriate language in user preferences but still in 
the menu UserPreferences are used instead of Polish translation 
PreferencjeUżytkownika. Same happens for MissingPage and other system pages. 
Moinmoin version 1.3.5. TIA
