Create a different way of using async/await in the AsyncAwait solution

[marijnz0r]

First of all I want to thank you for your work invested in this project and creating examples for the community. It has helped me a lot.
I want to suggest an improvement to the AsyncAwait solution.
Currently the only usage of the task-based asynchronous pattern is using a different thread to do work on. I think we can improve the solution by providing an example that uses the async and await keywords without introducing a new thread.

Current way:
await Task.Run(() => bst.MakeBreakfast());

Alternative way:
await bst.MakeBreakfastAsync();

This has the same result: work being done asynchronously and a responsive UI, but without an extra thread.

It requires a certain amount of extra code, but I would love to contribute to the project. Let me know if you would appreciate this.

Thanks! I appreciate you pointing that out. I made the change in the other two events after that one - btnMultipleThreads_Click and btnMultipleThreadsHeavy_Click - but I think I'll leave the one in btnSeparateThread_Click as-is.

It's been awhile since I wrote this, but making the change there would require changing the signature of the BreakfastSingleThread.MakeBreakfast() method, and I think I was trying to prevent touching it... to show what one could gain with a bare minimum of changes.
