Enabling to create new objects using another method (Ninject for example)

[jkvargas]

With this commit you can define a way on how grapevine will generate objects for you, follows an example using ninject:

IKernel kernel = new StandardKernel(new INinjectModule[] { new Whatever() });

Grapevine.Server.RestServer.CustomCreateInstance = (Type p) => { return kernel.Get(p); };
