Added the Windows API CodePack NuGet package to the solution

It'll be used to access some features in the Windows API, such as the task dialog and the jump list feature Windows 7 and higher.
Made the icons needed by the main window local instead of global

Since the icons are only going to be used by the main window, these icons do not need to be a global resource that'll be accessible to all forms/controls in the project.
Implemented event handlers when the app comes across an unhandled exception

In addition, implement an operating system check to see if certain features that we use in our app (such as the task dialog) is supported on the running platform or not.
