Things I learned during this project:

• Iterating over a parallel stream of a synchronized collection is not automatically thread-safe.
• Timer.schedule(...) vs Timer.scheduleAtFixedRate(...).
• To set an event handler on the entire window in TornadoFX, register it on the current stage during the View's onDock() method.
• To have fine control of multiple key presses at once, keep track of the keys pressed and released.
• If it's necessary to stop a thread that is currently sleeping, call its interrupt() method. Wherever the Thread.sleep() inside of that thread is executed must be wrapped in a try-catch block that handles InterruptedException.
• To make sure a thread stops when the main program has ended, set it to a daemon thread before execution.
• At the time of this writing, Travis CI doesn't have a text area where you can input multiline environment variables. They only provide a text field. To get around this, simply replace new lines with \n, then prefix the string with $' and append ' (e.g. $'like\nthis').
