    Replace "system" with system languages when setting spelling dictionaries
    
    The string "system" is used as a placeholder for the default system
    languages in the preference listing of  spelling dictionaries. Before
    sending this to WebKit to set the spelling dictionaries, we should
    fill in the actual default system languages.
