CoBrowser.net Load Control script

Helper Class to help control when the CoBrowser.net script should be loaded and/or to resume chat on pages that normally dont contain the CoBrowser.net script.

@example:
var _cb = new CobrowserChatApi();
_cb._includeCobrowser(); //loads the script if not already loaded

@example:
var _cb = new CobrowserChatApi();
_cb.startChat('#mychatconfig', function(available){
    if (available){
        console.log('chat was started');
    }
});
