        Fix some object lifetime issues in these two commands. This fixes some crashes
        I am seeing in some new code I am working on, but have not yet reproduced otherwise.

        * khtml/editing/htmlediting.cpp:
        (khtml::InsertParagraphSeparatorCommand::~InsertParagraphSeparatorCommand): No longer deref nodes
        in the ancestor list. They are not ref'ed when put on list. D'uh.
        (khtml::InsertParagraphSeparatorCommand::doApply): Ref all cloned nodes that are created by the command
        before putting them on the cloned nodes list. This are still deref'ed in the destructor.
        (khtml::InsertParagraphSeparatorInQuotedContentCommand::~InsertParagraphSeparatorInQuotedContentCommand): Ditto
        destructor comment.
        (khtml::InsertParagraphSeparatorInQuotedContentCommand::doApply): Ditto doApply comment.
