        <rdar://problem/5714333> Add document.getSelection()

        Add a synonym for window.getSelection() that FF supports.  There were requests in
        this bugs dupes to also support the IE only document.selection, but IE's Selection
        object is too different than ours currently for that to be safe (specifically, we
        don't support enough of IE's TextRange methods on our DOM Range object yet). I
        filed <rdar://problem/5761233> to cover that.

        * dom/Document.cpp:
        (WebCore::Document::getSelection): Added.
        * dom/Document.h:
        * dom/Document.idl: Ditto.  JS only since this is about web compatibility.
