Refactor: Move all initialization logic out of api_server and into init (#91)

* Zeroconf logging improvements

* Ignore RuntimeErrors in background threads - Prevents issues during shutdown

* Migrate start up code from api_server.py to init.py

* Add error handlers to the API server to handle detached instances

* Integrate RenderQueue eval loop into RenderQueue object

* Silently catch RuntimeErrors on evaluate_queue

* Stop background queue updates in prepare_for_shutdown
