    Add check_yes_no() to test boolean img properties · 52572781

    Use check_yes_no() to test if a boolean property is set.
    
    Although the documentation states that to set a boolean image property
    you need to assign the "yes" value to it, this function will accept
    "yes", "true", 1, "on" and "set" in a case-insensitive way and reject
    "no", "false", 0, "off" and "unset".
    
    An empty or not-set variable is treated as false.
    
    An unknown value will raise a warning but will be accepted. This is done
    to protect the users because prior to this commit, in some cases we only
    tested if an image property had a non-empty value.
    
    This resolves #80
