New MVC async controller

[PureKrome]

With the new async/await code now pushed up to the dev branch, a new MVC async controller is needed.

@phillip-haydon I've reassigned myself to this because I've just abstracted the module/controller logic into a seperate new class ... after all.. the logic is identical.. it's only the 'web' parts that differ (eg. session/response results).

So once I've finished migrating my nancy module to remove all the logic and then reference this new class, i'll make the MVC controller.

Okie dokie!

Is there any other Nancy stuff blocking you? Or is it all good now? Trying to figure out when the next Nancy release is atm.

There's no other Nancy stuff blocking me right now. So far - it's all good baby!
