Fixed Issue 212: Incorporate patch to add URL links to GL javadoc

Incorporated patch from user cylab on javagaming.org forums to
generate @native tags in GL javadoc which are postprocessed using a
taglet:
  http://www.javagaming.org/forums/index.php?topic=12629.0
Modified supplied patch to restrict the @native designation to only
the function name, and to understand OpenGL data type-related suffixes
(i.e., glVertex -> glVertex3f).
