[feature request] sending messages to jweb

@Yaniki
I've some good news: this is already available. Unfortunately the documentation of the initial Max 7 release doesn't include the details but here is something to get you started:

    // Communicating with Max from within jweb
    ---
    
    In Max 7 jweb uses the Chromium Embedded Framework (CEF) for running websites within a Max box. What's new is that you can communicate with the JavaScript of the shown website. Please note that since CEF is in a seperate process, the communication is inherently asynchronous, and you can't rely on having sent and outputted messages within the same event.

    // Receiving messages from Max
    ---

    The bindInlet function enables listening to messages being sent to the jweb object from within the JavaScript of the webpage. In order to do that you attach a callback function to certain messages as shown in the example below:

        window.max.bindInlet('doSomething', function () {
            /*
             * trigger functionality without arguments
             *
             * message 'doSomething'
            */
        });
        

    If you'd like to send messages with arguments to the website simply send a list of space delimited values to the jweb object as shown below. You can either access these values as parameters in your listener callback function or use the array-like arguments object if the amount of parameters might vary.
    
        window.max.bindInlet('doSomethingWithArgs', function (a, b) {
            /*
             * if a fixed set of parameters doesn't meet
             * your needs you can use the array-like arguments
             * objects in order to gain access to the
             * incoming parameters
             *
             * message: doSomethingWithArgs 1 2
             */
        });
    

    // Sending messages to Max
    ---

    Using the outlet function you can output messages from the JavaScript of the shown webpage to the jweb's first outlet.

        // output a string
        window.max.outlet('foo');

        // output a list
        window.max.outlet('foo', 1, 2);

        // output contents of array with prepended 'foo' message
        var ar = [1, 2, 3, 4];
        window.max.outlet.apply(window.max, ['foo'].concat(ar));

    Additionally you can send messages to Max using the href attribute of an anchor tag if following a certain but simple syntax. Note that a message send this way will be outputted with a prepended 'maxmessage'.
    
        

    // Interacting with Max dictionaries
    ---

    Using getDict you can access the contents of a Max dict object from within a website's JavaScript.

        var nestedValue;

        // access dictionary
        window.max.getDict('dictName', function(dict) {
            // dict is a JS object, so you can do things like
            nestedValue = dict.a;
        });

    If you like to set the contents of a dictionary within Max you can use the the setDict function to do that.
        
        var obj = {
            a : '1',
            b : '2',
            c : '3'
        };

        window.max.setDict('dictName', obj);
