Feature/toasts

[JBraunsmaJr]

Implemented a basic toast system to allow user-feedback when actions happen.

As a developer, you need to do two things to invoke a toast notification. Inject + Add

@inject ToastService ToastService
// stuff
ToastService.Add("Your message");

// Specify Type
ToastService.Add("Your message", MessageSeverity.Warning);

The provider forms felt a bit dirty with the copy/pasta. Perhaps another effort could abstract them?
