Split up net.java.games.util; moved GLUT and BufferUtils into
net.java.games.jogl.util, and moved demo-specific utility classes into
jogl-demos project under demos.util. Added nearly all JavaOne demos
into jogl-demos project; rewrote where necessary to use
ClassLoader.getResourceAsStream() instead of flat files, put into
packages and added to Makefile. Added gleem to jogl-demos project.
Added jogl.jar build rule.
