schema-codegen: generate classes for interfaces on C#/Unity

[endel]

With Colyseus 0.13 coming out, and the new type-safe Send()/OnMessage() feature, it would be nice to avoid manually creating the same structures on both server-side and client-side in order for them to communicate.

The problem with generating classes for EVERY interface is that the schema-codegen may generate code for interfaces that aren't really related to message passing.

The ideal example of this feature is this:

interface SomeMessageType {
  bar: number;
}

//...

this.onMessage("foo", (client, message: SomeMessageType) => {
  // received `SomeMessageType`
});

And in the client-side (C#) you can use the generated class to send a message:

room.Send("foo", new SomeMessageType { bar = 10 })

Interfaces are going to be generated as classes in C#, only if the interface has Message on its name. (e.g. MyMessageType, SomeMessage, MessageSomething)

This may not be ideal, but at least it will work for now. If this causes problems later we can re-visit and have a different solution.
