3db6111394 1. Commit version 0.03 of emulator and tools: this version successfully performs a hardware load from the disk and initiates the MCP.
2. Redesign B5500Console.html to support the Power On, Power Off, Halt, and Load buttons, along with a primitive mechanism to drive the Normal/Control lights.
3. Implement relative URLs for the <script> elements. This is a work in progress.
