WIP #12: Added DamconCanvas, wireframed model, embedded in main windo…
…w/JFrame - Moved existing UI down to mimic built-in engineering console and make room for damcon and other sliders - The current process of creating a J3D Universe generates a Viewer which in turn generates its own JFrame (because it wasn't given a Canvas). We need to figure out how the default canvas is generated, make one ourselves, and pass that through (WIP function checked in as well but it doesn't work). In the worst case, we might be able to pass the J3D JFrame through to the console manager and just reuse it.
