        TinyMCE: Implement execCommand(formatBlock, ...)

        * WebCore.xcodeproj/project.pbxproj: Added FormatBlock.{h,cpp} to the project.
        * WebCore.vcproj/WebCore/WebCore.vcproj: Ditto.
        * bridge/mac/WebCoreFrameBridge.h: Added WebUndoActions
        * editing/CompositeEditCommand.cpp:
        (WebCore::CompositeEditCommand::moveParagraph): Added a preserveStyle bool.
        (WebCore::CompositeEditCommand::moveParagraphs): Ditto.  downstream() the start
        or else we'll move collapsed whitespace and uncollapse it.
        * editing/CompositeEditCommand.h:
        * editing/DeleteSelectionCommand.cpp:
        (WebCore::DeleteSelectionCommand::initializePositionData):
        (WebCore::DeleteSelectionCommand::handleSpecialCaseBRDelete): Don't update m_endingPosition
        because that's removeNode's responsibility.
        (WebCore::updatePositionForNodeRemoval): Added.
        (WebCore::DeleteSelectionCommand::removeNode): Turned removeFullySelectedNode into a virtual
        overload of removeNode so that we can update positions as we remove nodes.
        (WebCore::updatePositionForTextRemoval): Added.
        (WebCore::DeleteSelectionCommand::deleteTextFromNode):
        (WebCore::DeleteSelectionCommand::handleGeneralDelete):
        (WebCore::DeleteSelectionCommand::fixupWhitespace): Got rid of m_trailingWhitespaceValid
        since m_trailingWhitespace is always valid (we update it as we remove nodes).
        (WebCore::DeleteSelectionCommand::mergeParagraphs):
        (WebCore::DeleteSelectionCommand::doApply): Leading and trailing spaces should
        be fixed if they have collapsed before merging paragraphs.

        * editing/EditAction.h:

        * editing/FormatBlockCommand.cpp: Added.
        (WebCore::FormatBlockCommand::FormatBlockCommand):
        (WebCore::FormatBlockCommand::modifyRange): Similar to InsertListCommand::modifyRange().
