        - fix http://bugs.webkit.org/show_bug.cgi?id=16657
          Acid3 failure since table.caption and table.thead do not work for nodes added by appendChild
        - fix http://bugs.webkit.org/show_bug.cgi?id=16659
          Acid3 expects HTMLTableElement.rows to include a <tr> element that is an immediate child of the <table>

        * GNUmakefile.am: Added HTMLTableRowsCollection.
        * WebCore.pro: Ditto.
        * WebCore.vcproj/WebCore.vcproj: Ditto.
        * WebCore.xcodeproj/project.pbxproj: Ditto.
        * WebCoreSources.bkl: Ditto.

        * dom/XMLTokenizer.cpp: Took out stray include.

        * html/HTMLCollection.cpp:
        (WebCore::HTMLCollection::itemAfter): Removed all the table rows code, since we now use
        a separate class for that collection. Also got rid of the distinct types for custom collections
        that don't need them (use Other for both).
        * html/HTMLCollection.h: Also made firstItem non-virtual because it doesn't need to be virtual.

        * html/HTMLFormCollection.cpp:
        (WebCore::HTMLFormCollection::HTMLFormCollection): Use Other instead of FormElements
        for the HTMLCollection type.

        * html/HTMLTableElement.cpp:
        (WebCore::HTMLTableElement::HTMLTableElement): Eliminated m_head, m_foot, m_firstBody, and m_caption.
        (WebCore::HTMLTableElement::caption): Added non-inline version. Finds the caption rather than
        keeping a pointer to it.
        (WebCore::HTMLTableElement::setCaption): Rewrote.
        (WebCore::HTMLTableElement::tHead): Ditto.
        (WebCore::HTMLTableElement::setTHead): Ditto.
        (WebCore::HTMLTableElement::tFoot): Ditto.
        (WebCore::HTMLTableElement::setTFoot): Ditto.
        (WebCore::HTMLTableElement::createTHead): Ditto.
        (WebCore::HTMLTableElement::deleteTHead): Ditto.
        (WebCore::HTMLTableElement::createTFoot): Ditto.
        (WebCore::HTMLTableElement::deleteTFoot): Ditto.
        (WebCore::HTMLTableElement::createCaption): Ditto.
        (WebCore::HTMLTableElement::deleteCaption): Ditto.
        (WebCore::HTMLTableElement::lastBody): Added.
        (WebCore::HTMLTableElement::insertRow): Rewrote to use a loop based on code in HTMLTableRowsCollection.
        This is different from the old code mainly in how it handles rows outside any section.
        (WebCore::HTMLTableElement::deleteRow): Ditto.
        (WebCore::HTMLTableElement::addChild): Removed code to set the various members. Keeping pointers to
        these was a possible source of serious bugs too, including crashes with stale pointers, although I
        didn't write any test cases to prove those bugs existed.
        (WebCore::HTMLTableElement::parseMappedAttribute): Changed the rules code to visit all cells, not
        just the cells of the first body. I believe this fixed rendering on some table tests. I think the code
        visits too many cells and also the use of recursion is overkill, but I didn't try to fix that.
        (WebCore::HTMLTableElement::rows): Changed to use the new HTMLTableRowsCollection.
        * html/HTMLTableElement.h: Changed functions to return PassRefPtr, which can be important if strange
        things like DOM mutation events take things ot of the tree before they are safely referenced by
        JavaScript wrappers. Also changed functions to take PassRefPtr and added exceptions. Removed unneeded
        firstTBody and setTBody functions and childrenChanged function override, as well as unused Rules and
        Frame enums. Removed m_head, m_foot, m_firstBody, and m_caption, and added lastBody function. Removed
        unneeded friend declaration for HTMLTableCellElement.
        * html/HTMLTableElement.idl: Allow the setteres for caption, tHead, and tFoot to raise exceptions.

        * html/HTMLTableRowsCollection.cpp: Added. Implements the HTML 5 rule for which rows are in the
        collection in which order.
        * html/HTMLTableRowsCollection.h: Added.

        * loader/FTPDirectoryDocument.cpp:
        (WebCore::FTPDirectoryTokenizer::appendEntry): Use the standard insertRow function instead of
        coming up with our own way of inserting a row. Simplifies things -- we can remove the code to
        create a tbody element.
