13361	images fail when site path includes parentheses because background-image path in ckeditor.js needs single-quotes around url value	Jamie	Tomasz Jakut	"Images (e.g. non-sprite toolbar images such as JustifyLeft, JustifyCenter, etc.) fail to display when the full site path includes parentheses (common in Visual Studio debug mode; e.g. ""http://localhost:59847/(S(tlbjdb0xrjmmgdfeuii1hhdbaf5i))/"") because background-image path in ckeditor.js needs single-quotes around url value. 

To fix this, find the following code in ckeditor.js: 
   background-image:url(""+CKEDITOR.getUrl(a)+"");

...and change it to...
   background-image:url('""+CKEDITOR.getUrl(a)+""');

Note the added single-quotes immediately inside the parentheses. Problem solved.
