        Implement execCommand(Insert{Un}OrderedList)

        * WebCore.xcodeproj/project.pbxproj: Added InsertListCommand.{h,cpp} to the project.
        * dom/Position.cpp:
        (WebCore::hasRenderedNonAnonymousDescendantsWithHeight):
        Added. A block with height is only a candidate if this is false.  This should fix the problems
        getting carets into empty blocks.
        (WebCore::Position::inRenderedContent):
        * editing/AppendNodeCommand.cpp:
        (WebCore::AppendNodeCommand::doApply):
        * editing/CompositeEditCommand.cpp:
        (WebCore::hasARenderedDescendant):
        (WebCore::CompositeEditCommand::prune): A node can have DOM descendants that are rendered, yet
        have no rendered descendants.  Fixed the pruning rule to avoid removing a node like this.
        (WebCore::CompositeEditCommand::mergeIdenticalElements): Put the two elements next to
        each other if they aren't already, as a convenience.
        (WebCore::CompositeEditCommand::moveParagraph): Added code to preserve the current selection.
        (WebCore::CompositeEditCommand::moveParagraphs): Ditto.
        * editing/CompositeEditCommand.h:
        * editing/DeleteSelectionCommand.cpp:
        (WebCore::DeleteSelectionCommand::initializeStartEnd): Expansion for special elements should
        continue to happen until it is no longer possible.
        (WebCore::DeleteSelectionCommand::handleGeneralDelete): The code to adjust the start node
        wouldn't always avoid removing the start block.
        * editing/InsertListCommand.cpp: Added.
        (WebCore::InsertListCommand::fixOrphanedListChild): Puts a list item that isn't inside a list
        into a list.
        (WebCore::InsertListCommand::InsertListCommand):
        (WebCore::InsertListCommand::modifyRange):
        (WebCore::InsertListCommand::doApply):
        * editing/InsertListCommand.h: Added.
        (WebCore::InsertListCommand::):
        * editing/InsertNodeBeforeCommand.cpp:
        (WebCore::InsertNodeBeforeCommand::doApply):
        * editing/InsertParagraphSeparatorCommand.cpp:
        * editing/JSEditor.cpp:
        * editing/TextIterator.cpp:
        (WebCore::TextIterator::advance): Don't handle a node if the end of the range used to create the
        iterator ends at the start of that node.
        used to create the iterator.
        * editing/VisiblePosition.cpp:
        (WebCore::VisiblePosition::next):
        (WebCore::VisiblePosition::previous):
        * editing/VisiblePosition.h:
        Added a parameter to next/previous to prevent them from going outside the current editable region.
        * editing/htmlediting.cpp:
        (WebCore::highestAncestor):
        (WebCore::enclosingList):
        (WebCore::enclosingListChild):
        (WebCore::outermostEnclosingList):
        (WebCore::createListItemElement):
        * editing/htmlediting.h:
        * page/Frame.cpp:
        (WebCore::Frame::selectionListState): Added.
        * page/Frame.h:
