Added methods to GetWidgetRenderingMode and SetWidgetRenderingMode in nsPresContext Removed NS_GFX_RENDER_FORM_ELEMENTS define, now it uses the GetWidgetRenderingMode method on the rendering context. Resurrected Rod's listbox frame-based widget code. Added -moz-option-selected pseudo attribute to control the appearance of selected items for the listbox frame-based widget. Added a style rule with attribute selector for -moz-option-selected to the ua.css style sheet. Modifed nsView::SetVFlags to do a bitwise or instead of bitwise and to set flags. Modified nsView::HandleEvent to compare mVFlags with NS_VIEW_FLAG_DONT_CHECK_CHILDREN
