EventBus Usage in Caves of Zircon

[bayou-brogrammer]

Is your feature request related to a problem? Please describe.
The event bus was moved from the singleton object Zircon and onto the application state instead. I am following the cavesofzircon tutorial and I am trying to figure out how to create the logging system using the event bus

Describe the solution you'd like
A way to have the application be a singleton in the game

Describe alternatives you've considered
I was going to create a singleton class myself that just slapped the app into it and just query from there, but it seems rudimental and wrong
