在xml中加入圖片，發佈JetBrains Plugin的圖文並茂description

有時候我們在JetBrains發佈插件時，需要加入一些圖片到plugin.xml的description標籤使得“圖文並茂”，like this：

這時候，我們可以藉助html標籤來實現，在description中插入CDATA 區段，添加如下示例代碼：

    <description><![CDATA[
      Generate Null Object for object:<br>
      Provide an object as a surrogate for the lack of an object of a given type.<br>
      The Null Object provides intelligent do nothing behavior, hiding the details from its collaborators.<br>
