Edited Feature: 3 typos in Backgrounds.css leading to 404s [27934]

Hi team,

I have identified 3 typos in file AjaxControlToolkit\Styles\Backgrounds.css leading to 404s instead of the referenced .gif files

- line 104 (missing ".gif")
Actual : background-image: url('<%=WebResource("AjaxControlToolkit.Images.Tabs.ActiveLeft-VerticalLeft")%>');
Fixed : background-image: url('<%=WebResource("AjaxControlToolkit.Images.Tabs.ActiveLeft-VerticalLeft.gif")%>');

- line 184 (too many double quotes)
Actual : background-image: url('<%=WebResource(""AjaxControlToolkit.Images.Tabs.Bottom-ActiveLeft.gif"")%>');
Fixed : background-image: url('<%=WebResource("AjaxControlToolkit.Images.Tabs.Bottom-ActiveLeft.gif")%>');

- line 188 (too many double quotes)
Actual : background-image: url('<%=WebResource(""AjaxControlToolkit.Images.Tabs.Bottom-Active.gif"")%>');
Fixed : background-image: url('<%=WebResource("AjaxControlToolkit.Images.Tabs.Bottom-Active.gif")%>');
