Command-line overrides for props are not removed from ARGV

[grtjn]

util.rb, load_prop_from_args should remove args matching the --ml.xx= pattern. I was able to fix that by copying these two lines from the find_arg function, and adding those after the if a.match...:

      index = ARGV.index(a)
      ARGV.slice!(index)
