Got the speed readout working, depth readout, a basic message log system started (one at a time for now, need to figure out how to make a log that appends messages line by line), simple audio, periscope overlay with zooming in/out, and the simple submarine dynamics from before.

Next up: Get the periscope camera to move up/down with [ins]/[del]
