[FIXED][3.0] JSON usage in JsonReader and TreeLoader

[stever]

I think JsonReader.read ought to use the Ext JSON functionality rather than calling eval.

Original:

    read : function(response){
        var json = response.responseText;
        var o = eval("("+json+")");
        if(!o) {
            throw {message: "JsonReader.read: Json object not found"};
        }
        return this.readRecords(o);
    } 

Proposed:

    read : function(response){
        var o = Ext.decode(response.responseText);
        if(!o) {
            throw {message: "JsonReader.read: Json object not found"};
        }
        return this.readRecords(o); 

Same thing in TreeLoader.processResponse.
