JOGL Website Updates & Docs

Beautified the JOGL Test Applet page and replaced the applet-tag with a object-embed mixed one.

Added a little a NEWT Overview writeup.

.. and fixed the html code a bit.

This just reminds me about previous code changes in regards to the Gears ES1 | ES2 test code.
Their common VBO code[v2.0-rc3] uses interleaved arrays,
which is now possible with our managed VBO util GLArrayDataServer.
