Adds support for sound effects in Doodle and configures some for various doodads to start out with: * Buttons and Switches: "Clicked down" and "clicked up" sounds. * Colored Doors: an "unlocked" sound and a "door opened" sound. * Electric Door: sci-fi sounds when opening and closing. * Keys: sound effect for collecting keys. JavaScript API for Doodads adds a global function `Sound.Play(filename)` to play sounds. All sounds in the `rtp/sfx/` folder are pre-loaded on startup for efficient use in the app. Otherwise sounds are lazy-loaded on first playback.
