fl-build-report: error: Error in option "--stylesheet-path":
    AttributeError: 'str' object has no attribute 'pop'

After digging into the code, found docutils (0.10) needs the value of "--stylesheet-path" a "comma_separated_list" (line 74, docutils/writers/html4css1/init.py), but funkload only give it a string, so cause the problem, here is the patch to fix:
