        Add a test to make sure copying from a list and pasting into a list
        keeps the list at the same indention level rather than nesting.

        When pasting a list into another list should not indent another level.
        If the cursor is at the beginning of the line, it should insert the
        list items before the current list item.  If the cursor is at the end
        of the line, it should insert the list items after the current list item.

        This matches Firefox and IE and makes the common activity of reordering a list
        work as expected.

        This also adds a small helper method (isListItem) to htmlediting.h.
