JavaScript equivalent of java.net.URLEncoder.encode(String s)
(from Java Docs:-)
1.The ASCII characters 'a' through 'z', 'A' through 'Z', and '0'
  through '9' remain the same.
2.The space character ' ' is converted into a plus sign '+'.
3.All other characters are converted into the 3-character string
  "%xy", where xy is the two-digit hexadecimal representation of
  the lower 8-bits of the character.


usage: var coded = URLEncoder(string);


JavaScript equivalent of java.net.URLDecoder.decode(String s)
1.Exact reverse of java.net.URLEncoder.encode(String s)


usage: var decoded = URLDecoder(string);


Note: prior to JScrip 5.5 String.replace() will not accept a function
as it's second parameter so the function set-up will try to compensate.
