    tests: add a way to ignore png creation and html logging
    
    For certain files, we just want to know if lasem doesn't crash, we are
    not interested in the actual output. This patch allow to not save the
    result as png and to not include the result in the html log file.
    
    Just prepend "dont-render-" to the file name.
