some suggestion to simplify the json output

[floyd]

1. can you omit 'null' value in serialization or make it configable by any way

2. Besides,i need the key in json-map to be left un-quoted(quotes of the key are unnecessary for me at all) after serialization.can you add this feature??

the following is the code Snippets from jsonobject apapted by me :).
------------------------------------------------------
private static boolean addQuote = System.getProperty("net.sf.json.toString.addQuote")!=null;
   public String toString() {
      ...
            Object o = keys.next();
            if (addQuote){
                sb.append( JSONUtils.quote( o.toString() ) );
            }else{
                sb.append(  o.toString()  );
            }
      ...
  }
------------------------------------------------------
i'm using json-lib 2.2.2

Floyd,

#1 You can skip properties by setting a JsonPropertyFilter on a JsonConfig instance
jsonConfig.setJsonPropertyFilter(PropertyFilter jsonPropertyFilter)

#2 can be solved by calling WebUtils.toString(JSON) no need to change JSONObject
