Implemented the methods to customize tdlib parameters

Now the EasyClient constructor does not directly start TDLib, you must always use the create() method (e.g. "var client = new BotClient("791655237:AAEs1bgsn9kL8jnj-aXSOEaGgZaTS_iXjkI").create();")
Now can be specified the name and lastname (only for UserClient) of the user to be used during registration through the UserClien constructor
