Steam Engine Simulator

The Steam Engine Simulator shown on AngeTheGreat's YouTube channel.

[h3]Change Notes[/h3] - Added a pressure relief valve - Flywheel is now much heavier (slightly unrealistic for this size of engine but makes the game easier to play) - Audio when filling water is now smoother - Removing water from the tank previously didn't account for energy loss correctly - Made audio volume slightly quieter - Dampened some harsh audio frequencies - Renamed "throttle" to "throttle valve" and reversed number reading on information panel - Engine no longer makes an abrupt noise when the program is started
