urllib.urlencode small improvement

[Oleg Broytmann]

Hello!

   Currently urllib.urlencode takes dictionary {"x": "y", "u": "v"} and
produces encoded string as "x=y&u=v". But wat if I want to repeat some
keys: "x=y1&x=y2&u=v"? I cannot pass this to urlencode using dictionaries!

   The following patch adds the feature to urlencode: either dict or a list
(or tuple) of pairs (lists or tuples) can be passed to urlencode:

          k = quote_plus(str(k))
          v = quote_plus(str(v))
          l.append(k + '=' + v)
