Recursion loop if duplicate url() images on same line and fingerprinting disabled

[GoogleCodeExporter]

If you disable fingerprinting (as we do because we use the default servlet for 
images), and you have multiple image filenames on the same line in the CSS (a 
pre-minified library, or image sprites), JSCSSMergeServlet gets stuck in a 
recursion loop.

To reproduce, just use a css file with multiple url(file1.jpg) url(file1.jpg) 
on the same line.  It seems that when "fingerprinting" is enabled, it bypasses 
the problem, but we can't always use that.
Here's an example file: 
https://cdnjs.cloudflare.com/ajax/libs/chosen/1.1.0/chosen.min.css

I've replaced the processCSSLine method in 0.0.7 to handle this, feel free to 
use it if you want: http://pastebin.com/Zb7k7nFS

Thanks for the details about this problem and also the possible fix. I would 
check it out and merge the same in trunk for version 0.0.8.
