        <rdar://problem/4875189> List is deleted when replacing contents with Chinese/Japanese characters

        Moved from unsupported-content because we've supported editing lists
        for a while now:
        * editing/deleting/4875189-expected.checksum: Added.
        * editing/deleting/4875189-expected.png: Added.
        * editing/deleting/4875189-expected.txt: Added.
        * editing/deleting/4875189.html: Added.
        * editing/unsupported-content/list-delete-002-expected.checksum: Removed.
        * editing/unsupported-content/list-delete-002-expected.png: Removed.
        * editing/unsupported-content/list-delete-002-expected.txt: Removed.
        * editing/unsupported-content/list-delete-002.html: Removed.
        
        Reflects new behavior:
        * editing/deleting/delete-select-all-003-expected.checksum:
        * editing/deleting/delete-select-all-003-expected.png:
        * editing/deleting/delete-select-all-003-expected.txt:
        
        Ditto and also removed a FIXME:
        * editing/deleting/list-item-1-expected.checksum:
        * editing/deleting/list-item-1-expected.png:
        * editing/deleting/list-item-1-expected.txt:
        * editing/deleting/list-item-1.html:

        List is deleted when replacing contents with Chinese/Japanese characters

        * editing/htmlediting.cpp:
        (WebCore::isSpecialElement): Lists are no longer special.
        They can be removed by removing their content and then 
        then hitting delete inside of the empty list item that's 
        left over. Even when that list item is the first thing 
        in the editable region.
