Queue up events before the UI is spawned
- Queue up any events fired to the UI before the UI exists - At exit, check if UIs exist, and if not, flush the queue of LogRecords to the console directly. - When establishing a connection from the UI to the server, flush the queue of events to the queue in the server connection, so the UI will receive them when it begins its event loop.
