	- fixed 3108912 -- onclick handlers not supported on form elements

	We now pass the events back to the NSView here in WebCore; they pass through all the
	machinery in the DOM before getting sent on.

        * kwq/KWQKHTMLPart.h: Add widgetWillReleaseView and handleMouseDownEventForWidget functions,
	overrides for khtmlMousePressEvent, khtmlMouseDoubleClickEvent, khtmlMouseReleaseEvent, and
	a new _mouseDownView field.

        * kwq/KWQKHTMLPart.mm:
        (KWQKHTMLPart::KWQKHTMLPart): Initialize _mouseDownView to nil.
        (KWQKHTMLPart::khtmlMousePressEvent): Call handleMouseDownEventForWidget, but if it returns
	false call through to the base class function.
        (KWQKHTMLPart::khtmlMouseDoubleClickEvent): Ditto.
        (KWQKHTMLPart::handleMouseDownEventForWidget): Do a hit test to find out which view to send
	the mouse down event to, and then send it.
        (KWQKHTMLPart::khtmlMouseReleaseEvent): Send the mouse up event to the view we sent a mouse
	down event to, or call through to the base class otherwise.
        (KWQKHTMLPart::widgetWillReleaseView): Clear out the _mouseDownView field if the view is
	being released by the QWidget that owns it.

        * kwq/KWQWidget.mm:
        (QWidget::~QWidget): Call KWQKHTMLPart::widgetWillReleaseView.
        (QWidget::setView): Call KWQKHTMLPart::widgetWillReleaseView on the old view.

        * WebView.subproj/WebHTMLView.m: (-[WebHTMLView hitTest:]):
	Take over hit testing so that all clicks on subviews are handled by the WebHTMLView.
	WebCore now handles getting the mouse events to the subviews after passing
	the events through the DOM.
