First version of the new visualization tool

This commit adds a working version of the new visualization tool built
with Swing. It understands DSLabs objects better than the Oddity
visualizer and is more closely coupled. This tool is roughly at
feature-parity with Oddity. In a future commit, Oddity (and the
Json machinery) will be removed entirely.
