Add support for generic variance for post request handler.

Add support for generic variance for post request handler.

[jbogard]

Isn't it already variant?

The thing is that Mediator's GetPostRequestHandlers method returns handlers only with specific response type.

https://github.com/jbogard/MediatR/blob/master/src/MediatR/Mediator.cs#L97

It would work fine if there would be only one response type for all requests, but if requests have different responses, then have to make post request handler for each response type.

Do you have an example of a request/response with a post handler that isn't
currently firing appropriately?

Created sample:
https://github.com/marisks/mediatr-sample

Seems that notification handler is not firing too. I am using StructureMap as IoC and maybe haven't configured it properly:

Seems that generic versions has to be registered explicitly:
https://github.com/jbogard/MediatR/blob/master/src/MediatR.Examples.StructureMap/Program.cs#L35

Haven't seen that sample before.

Thanks for help and great library!
