Travis test harness for hobby operating systems

This Travis configuration runs an operating system in various emulators. It can execute a SikuliX test script to ensure that some elements are visible on-screen, send keystrokes and mouse events, and interact with the OS GUI in an automated way. Finally, it will take screenshots of the operating system, and upload them to a separate repository hosting these artifacts.

Below are screenshots of an example operating system. This example merely displays a gradient and does not process any user input.
