Move to JOGL 2 and new Java 3D. [1423]

This is preparation for the Java 7+ move…though this change in
particular should work fine with Java 6.

You are going to want to run “ant clean” after pulling this change!
This will also require people using IDEs to have to reset the locations
of their JAR files. Sorry. :( All platform independent JARs will be in
“./lib/share”, and the platform specific JARs will be in their
respective subdirectories of “./lib”.

OS X Users: you should probably check for the presence of Java 3D in
one of the java.ext.dirs directories. For me, these are:

* ~/Library/Java/Extensions
* /Library/Java/Extensions
* /System/Library/Java/Extensions
*
/Library/Java/JavaVirtualMachines/1.6.0_51-b11-457.jdk/Contents/Home/lib
/ext

If you find j3dcore.jar, j3dutils.jar, or vecmath.jar you should
temporarily move them. That way you can be sure you're running with the
JARs shipped in this pull request.

You can check for whether or not things are working by Help>About
McIDAS-V>System Information and the Java 3D version should be something
like:

1.6.0-pre10-daily-experimental daily

Assuming, of course, that you were able to successfully start McV! I'm
cautiously optimistic and therefore not anticipating too many problems.

Good luck!
