use base64 encoded image instead of hard link

There is a link in the css file to ../images/loading.gif.  This forces a 
specific setup or requires changing the file.  It'd be much more flexible to 
just change the background to:

background: #fbfbfb 
url(data:image/gif;base64,R0lGODlhEAAQALMMAKqooJGOhp2bk7e1rZ2bkre1rJCPhqqon8PBud
