Subject: Bug 754 - Remove Ubuntu fonts from jogl-all.jar, provide it
 separately to reduce footprint for the masses.

Remove the ubuntu fonts from atomic/jogl-util-graph.jar and hence all derivated 'all' JAR files.
The Android jar files still contain the fonts as assets!

atomic/jogl-util-graph-fonts-p0.jar contains the fonts and is either referenced by:
  - UbuntuFontLoader: Using class based Jar URI derivation using TempJarCache to [down]load
    and extract the jar file (similar to native lib-loading).

  - Explicitly via traditional classpath, see jnlp-files/jogl-applet-runner-newt-GraphTextDemo01b-napplet.html

The pack200 jogl-all.jar file is now below 1MB
