DuiDesigner修改：增加对RichEdit控件属性的保存

当资源中有RichEdit时，无论怎么样修改其属性，最终保存时并不会被写到XML中去，仅仅是一个节点：<RichEdit />，属性一概没有保存。
通过动态跟踪xml保存的调用过程，定位到函数：CLayoutManager::SaveProperties：switch(pExtended->nClass)    {case classControl:        SaveControlProperty(pControl, pNode);        break;    case classLabel:    case classText:        SaveLabelProperty(pControl, pNode);        break;    case classButton:        SaveButtonProperty(pControl, pNode);        break;    case classEdit:        SaveEditProperty(pControl, pNode);        break;    case classOption:        SaveOptionProperty(pControl, pNode);        break;    case classProgress:        SaveProgressProperty(pControl, pNode);        break;    case classSlider:        SaveSliderProperty(pControl, pNode);        break;    case classCombo:         SaveComboProperty(pControl, pNode);        break;    case classList:        SaveListProperty(pControl, pNode);        break;    case classListContainerElement:        SaveListContainerElementProperty(pControl, pNode);        break;    case classListHeaderItem:        SaveListHeaderItemProperty(pControl, pNode);        break;    case classActiveX:        SaveActiveXProperty(pControl, pNode);        break;    case classListHeader:        SaveListHeaderProperty(pControl,pNode);        break;    case classContainer:    case classVerticalLayout:        SaveContainerProperty(pControl,pNode);        break;    case classTabLayout:        SaveTabLayoutProperty(pControl, pNode);        break;    case classHorizontalLayout:        SaveHorizontalLayoutProperty(pControl, pNode);        break;    case classTileLayout:        SaveTileLayoutProperty(pControl, pNode);        break;    case classChildLayout:        SaveChildWindowProperty(pControl,pNode);        break;    case classWebBrowser:        SaveWebBrowserProperty(pControl,pNode);        break;    default:        break;    }
其中并没有处理对RichEdit的保存，问题就出现在这里，考虑增加一个函数SaveRichEditProperty，关键还要动态跟踪出RichEdit的pExtended->nClas是多少，动态发现是100。这些枚举值被定义在stdafx.h头文件中：
//UI classenum UIClass{    classPointer=100,    classWindow,    classControl,    classButton,    classEdit,    classLabel,    classText,    classOption,    classCombo,    classList,    classSlider,    classProgress,    classActiveX,    classContainer,    classVerticalLayout,    classHorizontalLayout,    classTabLayout,    classTileLayout,    classListHeader,    classListHeaderItem,    classListTextElement,    classListLabelElement,    classListExpandElement,    classListContainerElement,    classItem,    classScrollBar,    classChildLayout,    classWebBrowser};
100刚好等于classPointer，其实不太好，为了不影响后面的改动，暂时改为：
//UI classenum UIClass{    classPointer=100,    classRichEdit = 100,    classWindow,    classControl,    classButton,    classEdit,    classLabel,    classText,    classOption,    classCombo,    classList,    classSlider,    classProgress,    classActiveX,    classContainer,    classVerticalLayout,    classHorizontalLayout,    classTabLayout,    classTileLayout,    classListHeader,    classListHeaderItem,    classListTextElement,    classListLabelElement,    classListExpandElement,    classListContainerElement,    classItem,    classScrollBar,    classChildLayout,    classWebBrowser};

CLayoutManager::SaveProperties中增加：
case classRichEdit:        {            if ( strClass.Compare(DUI_CTR_RICHEDIT)==0 ) {                SaveRichEditProperty(pControl, pNode);            }        }        break;
并实现SaveRichEditProperty：
void CLayoutManager::SaveRichEditProperty(CControlUI* pControl, TiXmlElement* pNode){ SaveControlProperty(pControl, pNode); CRichEditUI* pRichEditUI = static_cast<CRichEditUI*>(pControl->GetInterface(DUI_CTR_RICHEDIT)); pNode->SetAttribute("multiline", "true"); pNode->SetAttribute("autovscroll", "true"); pNode->SetAttribute("vscrollbar", "true");  if(pRichEditUI->IsReadOnly())  pNode->SetAttribute("readonly", "true"); if ( pRichEditUI->IsRich() ) {  pNode->SetAttribute("rich", "true"); }}
RichEdit常用的几个属性保存一下，当然不保证是全的，如果有遗漏的可以再加。
