#5 Non-3d mode

[Zach Hoeken]

Currently, the Java3d software (and thusly RepRap) require you to use 3D, and therefore will not work unless you have a proper graphics card. It should be possible to run the control software without the 3D output option. Some core functionality that would be nice is:

* circuit board testing
* actual printing (from a pre-sliced file)
* slicing and dicing (might not be possible... but would still be nice)
