        Finish off spellchecking support to HTML editing. Includes work to
        enable continuous spellchecking.

        * khtml/editing/htmlediting_impl.cpp:
        (khtml::EditCommandImpl::markMisspellingsInSelection): Basically, a one-liner convenience to
        make the call over to the KWQKHTMLPart.
        (khtml::ReplaceSelectionCommandImpl::doApply): Did some rearranging of code so that the
        inserted content can be spell-checked. The function is basically the same, except for
        the addition of calls to markMisspellingsInSelection.
        (khtml::TypingCommandImpl::markMisspellingsAfterTyping): New function. Takes a look at the
        selection that results after typing and determines whether it needs to spellcheck.
        Since the word containing the current selection is never marked, this does a check to
        see if typing made a new word that is not in the current selection. Basically, you
        get this by being at the end of a word and typing a space.
        (khtml::TypingCommandImpl::typingAddedToOpenCommand): Call markMisspellingsAfterTyping.
        * khtml/editing/htmlediting_impl.h: Add new function declarations.
         * khtml/khtml_part.cpp:
        (KHTMLPart::setSelection): Since spell checks are updated when the selection changes,
        and every selection change passes through here, this is a good place to put the call
        to the spellchecker.
        * khtml/rendering/render_text.cpp:
        (InlineTextBox::paintMarker): Remove temporary misspelling line drawing code. Replace with
        call that does AppKit-style drawing. Fix up some comments.
        * khtml/xml/dom_docimpl.cpp:
        (DocumentImpl::addMarker): Repaint the node that had the marker added. This makes it show
        up on setting it.
        (DocumentImpl::removeMarker): Ditto.
        (DocumentImpl::removeAllMarkers): New function. Convenience for clearing all markers.
        Used when not in continuous spellchecking mode.
        (DocumentImpl::shiftMarkers): Moves markers in response to changes in a node's contents.
        This shifts the marker offsets by a given amount. This keeps the markers in the right
        place when a user types in a node with markers already set on it.
        * khtml/xml/dom_docimpl.h: Added new functions. Removed unnecessary enum qualifier from some
        declarations.
        * khtml/xml/dom_position.cpp:
        (DOM::Position::previousWordBoundary): This function was susceptible to endless loops...and
        needlessly so. Basically, if the current position is at a word boundary, run the code again
        to find the previous word boundary.
        (DOM::Position::nextWordBoundary): Same as above, but for next word boundary.
        * khtml/xml/dom_textimpl.cpp:
        (CharacterDataImpl::setData): Call shiftMarkers to update markers when this node changes.
        (CharacterDataImpl::insertData): Ditto.
        (CharacterDataImpl::deleteData): Ditto.
        (CharacterDataImpl::replaceData): Ditto.
        * kwq/KWQKHTMLPart.h:
        * kwq/KWQKHTMLPart.mm:
        (KWQKHTMLPart::advanceToNextMisspelling):
        (KWQKHTMLPart::markMisspellingsInSelection):
        (KWQKHTMLPart::updateSpellChecking):
        (KWQKHTMLPart::respondToChangedSelection):
        * kwq/KWQPainter.h:
        * kwq/KWQPainter.mm:
        (QPainter::drawLineForMisspelling): New function. Call over to WebKit to do the drawing.
        * kwq/WebCoreBridge.h:
        * kwq/WebCoreBridge.mm:
        (-[WebCoreBridge alterCurrentSelection:direction:granularity:]): Pass markMisspellings flag to
        setSelection call.
        * kwq/WebCoreTextRenderer.h:
