    Bracket matching: update bracket highlighting on context class changes
    
    In a C file, type:
    foo ("(ab)
    
    Before this commit, the ) matched with the first (. It's because the
    string context class is not updated directly.
    
    To fix it, the bracket highlighting is now updated when the
    highlight-updated signal is emitted.
    
    If it causes performance problems, the bracket highlighting can be
    temporarily disabled (e.g. on file loading). Or updating the bracket
    highlighting can be done in an idle or timeout function.
