remove Query and QueryAsync methods

[prabirshrestha]

Query and QueryAsync made more sense when using with fql. but now with graph api it is very simple. (fb c# sdk supports the following codes since https://github.com/facebook-csharp-sdk/facebook-csharp-sdk/tree/f1f1cebc73111bea5e9f5268befb8baf0779f637)
also issue #8 would cause breaking changes anyway.

Here is the new way to execute fql using graph api.

Single FQL:

var result = fb.Get("fql", new { q = "SELECT uid from user where uid=me()" });

MultiQuery FQL:

var resultMulti = fb.Get("fql", new
                                    {
                                        q = new[]
                                                {
                                                    "SELECT uid from user where uid=me()",
                                                    "SELECT name FROM user WHERE uid=me()"
                                                }
                                    });

Named multi-query:

var resultMultiNamed = fb.Get("fql",
                            new
                                {
                                    q = new
                                    {
                                        id = "SELECT uid from user where uid=me()",
                                        name = "SELECT name FROM user WHERE uid IN (SELECT uid FROM #id)",
                                    }
                                });

Here is the how to execute fql using async methods.

Single Query

var fb = new FacebookClient(accessToken);
var mrs = new ManualResetEvent(false);

fb.GetCompleted += (o, e) =>
                        {
                            if (e.Cancelled)
                            {
                                Console.WriteLine("cancelled");
                                return;
                            }
                            else if (e.Error != null)
                            {
                                Console.WriteLine(e.Error.Message);
                                return;
                            }

                            var result = e.GetResultData();
                            Console.WriteLine(result.ToString());
                        };

fb.GetAsync("fql", new { q = "SELECT uid from user where uid=me()" });

MultiQuery

var fb = new FacebookClient(accessToken);

fb.GetCompleted += (o, e) =>
{
    if (e.Cancelled)
    {
        Console.WriteLine("cancelled");
        return;
    }
    else if (e.Error != null)
    {
        Console.WriteLine(e.Error.Message);
        return;
    }

    var result = e.GetResultData();
    Console.WriteLine(result.ToString());
};

fb.GetAsync("fql",
            new
                {
                    q = new[]
                            {
                                "SELECT uid from user where uid=me()",
                                "SELECT name FROM user WHERE uid=me()"
                            }
                });

Named MultiQuery

var fb = new FacebookClient(accessToken);

fb.GetCompleted += (o, e) =>
{
    if (e.Cancelled)
    {
        Console.WriteLine("cancelled");
        return;
    }
    else if (e.Error != null)
    {
        Console.WriteLine(e.Error.Message);
        return;
    }

    var result = e.GetResultData();
    Console.WriteLine(result.ToString());
};

fb.GetAsync("fql",
            new
                {
                    q = new
                            {
                                id = "SELECT uid from user where uid=me()",
                                name = "SELECT name FROM user WHERE uid IN (SELECT uid FROM #id)",
                            }
                });
