Adaption of Oracle's Deployment changes, i.e. >= 7u51

Sadly, due to Oracle's Java Applet Plugin update 7u51,
unsigned applets are no more allowed and effectively
lower the bar to create user applets with raised privileges.<br/>
Hence JogAmp Community <b>signs</b> jogl-all.jar and gluegen-rt.jar, which contain the
JOGL's supporting classes as well as jogl-test.jar, which contains the applet class.<br/>
jogl-test.jar's manifest file uses <i>Permissions: sandbox</i>
to <b>not raise privileges</b>.
JNLP/Applets: Remove 'sun.java2d.noddraw' - We don't test with these flags either ..
JOGL Test Applets: Refine html pages
