The Switch and Harp Update

[list] [*]Added a new melodic instrument: the harp. [*]Added the Switch, the first of the logic systems. This is a first pass, and the model is temporary. [*]When the Switch is hit with a ball, it will teleport the ball to one of two outputs, and it will toggle between the outputs to send the ball to each time it is hit. [*]Revamped the color system for instruments. [*]Added some longer (multi-measure) timing options for Launchers. [*]Reworked the lighting to make the platforms stand out a bit more. [*]Added a Silent instrument for redirecting. [*]Renamed "Launchers" to "Utilities". [*]Added Crow. [/list]
