        Implemented command to insert a block in response to typing a return key (even though
        I am not turning that on by default with this patch....that will come later).

        This new command is called InsertParagraphSeparatorCommand.

        Reworked the command and function names associated with inserting content into a
        document. Before this patch, there were inputXXX and insertXXX variants, with the
        former used for more high-level actions and the latter used for lower-level stuff.
        However, this was confusing as the AppKit uses insertXXX for everything. This resulted
        in an insertXXX command going through an inputXXX WebCore step and then finally to an
        insertXXX WebCore step. To make this less confusing, I have changes all the names to
        be insertXXX, and modified the lower-level operations so that it is clear what they do.

        In order to do apply block properties, "regular" style declarations need to do style

        (CSSStyleDeclarationImpl::copyBlockProperties): New helper. Just like copyInheritableProperties
        except that it uses a different set of properties that apply only to blocks.
        (CSSStyleDeclarationImpl::copyPropertiesInSet): New helper that looks at a style declaration
        and copies out those properties listed in a pre-defined set.

        (khtml::ApplyStyleCommand::doApply): Much refactoring in this class to divide up the work of
        style changes into different kinds. CSS specifies certain properties only apply to certain

        (khtml::StyleChange::usesLegacyStyles):
        (khtml::EditCommand::setEndingSelectionNeedsLayout): New function to that tells the ending selection
        it needs to layout, even though it has not changed position in the DOM. For instance, this is needed
        when text align changes.
        * khtml/khtml_part.cpp:
        (KHTMLPart::setTypingStyle): Put in an early bail-out in the case where the current style matches
        the passed-in argument.
        (KHTMLPart::applyStyle): Modify this function so that block styles are applied when the selection
        is a caret. Formerly, this just set typing style and made no visible changes to the document.

        Fix for this bug:

        <rdar://problem/3816768> REGRESSION (Mail): Deleting last character in block incorrectly
        moves caret out of block.

        The issue here is that an empty block with no explicit height set by style collapses
        to zero height, and does so immediately after the last bit of content is removed from
        it (as a result of deleting text with the delete key for instance). Since zero-height
        blocks are not eligible caret positions, the caret jumped to the closest eligible spot.

        The fix is to detect when a block has not been removed itself, but has had all its
        contents removed. In this case, a BR element is placed in the block, one that is
        specially marked as a placeholder. Later, if the block ever receives content, this
        placeholder is removed.

        Also, do some cleanup on some old, crufty code in the move logic that is just so clearly wrong
        (it's very clear that we needs to be able to move more than just text nodes). This may expose
        bugs, but these bugs needs to be filed and fixed, not ducked. Besides, undoing this silliness

        <rdar://problem/3836986> Delete code removes elements of table structure; can result in very broken-looking web pages

        * khtml/editing/htmlediting.cpp:

        row, section, or column.
        (khtml::CompositeEditCommand::removeFullySelectedNode): New helper that recurses into elements
        of table structure when doing deletes, rather than deleting the structure elements themselves.
        (khtml::DeleteSelectionCommand::moveNodesAfterNode): Do not move content between elements
        of table structure. We may want to revisit this some day, but this seems like the best behavior
        to me now.

        where needed.
        * khtml/editing/htmlediting.h: Add declarations for new functions.

        Fix for this bug:

        <rdar://problem/3834779> Mail crashes when editing HTML message - khtml::Selection::layout()

        * kwq/KWQKHTMLPart.mm:
        (KWQKHTMLPart::styleForSelectionStart): Table code seems to be more robust when the call to
        insert our style-checking node is done with an appendChild rather than an insertBefore. Note
        that this table-related problem was exposed by fixing Selection::layout(), which I did
        yesterday. This change simply improves things even more so that we do not crash in the
        scenario described in the bug.

        This is a partial fix to this bug:

        <rdar://problem/3832886> increase quote level on new mail document leads to immediate
        crash in caret painting code

        To eliminate the bad behavior for good, I have done some investigations in Mail code,
        and I have sent a suggested code change on to Grant. Basically, Mail can't add empty
        blocks (like blockquote elements used for quoting) to documents without giving those
        blocks some content (so they have a height).

        I added some other crash protections below.

        * khtml/editing/selection.cpp:
        (khtml::Selection::layout): Check for non-null position after calls to VisiblePosition, since
        the VisiblePosition constructors may fail to find a visible spot in the document. Also, add
        a couple position-has-renderer assertion checks.
        * kwq/KWQKHTMLPart.mm:
        (KWQKHTMLPart::styleForSelectionStart): Take out pos.isNotNull() assertion since VisiblePosition
        may not yield a position. This assertion is a holdover from before we had VisiblePosition.
        (KWQKHTMLPart::fontForSelection): Rearrange the code a little to deal with possible null results from
        calls to helpers.
