        [Mac] WebCore need to notify AppKit spell checker after user has modified autocorrected text.
        https://bugs.webkit.org/show_bug.cgi?id=57665
        <rdar://problem/7350477>

        We need to track how user modified an autocorrected word. If he changed it back to original
        text, we want to record AutocorrectionReverted response. And if he changed it to something
        else, we want to record AutocorrectionEdited response.

        To achieve this, we need to distringuish between text replacement caused by autocorrection
        from that due to other causes, such as reversion, text substitution, etc. So we added a new
        marker type "Autocorrected". We also need to be able to check for correction, even when we
        don't intend to actually carry out replacement. For this, we introduced a new TextCheckingOption
        value, "CheckForCorrection".

        We also added DocumentMarkerController::markersInRange() to retrieve a vector of markers in
        specified range, and of specified type.
