        Added InsertTab, InsertBacktab, InsertLineBreak, and InsertNewline to the editing command table.
        Added Event parameter to execCommand, and to all of the enabled and exec functions.  Right now,
        the event is only used by the newly added commands.  But in the future, many (and possibly all) of
        these editing commands will need to consider the event so they are applied to the correct selection.

        Removed _insertTextWithEvent, _insertNewlineWithEvent, and _insertTextWithEvent.
        Instead, use execCommand and insertText methods on the Editor.
