Added Ant build support, contributed by Rob Grzywinski and Artur

Biesiadowski. Modified their original build.xml to understand
dependencies between build phases (to avoid full rebuilds each time)
and to invoke the C compiler without requiring an external Makefile.
At this point the old Makefile/Makefile2 pair is obsolete and will be
deleted shortly, as soon as the Ant build has been tested on Linux and
Mac OS X. Additionally, Cygwin is no longer needed for the build; the
documentation will be updated to reflect this. Refactored some of the
stub_includes files to be common between platforms, yielding a build
process cleanup. Fixed bugs in Javadocs.

+   - A clean download of JOGL is required for this build.

+   - This build has no dependence on environment variables; the needed

+   - script, by the virtual machine, or elsewhere. However, on all platforms,
+   - the C compiler and linker should be in the path. All other paths that
+   - need to be set are in host.properties.
+   -
+   - NOTE:  because the GlueGen config files have their own relative paths
+   -        which cannot be overridden by GlueGen, GlueGen MUST be run from
+   -        the "make" directory. This also means that this build.xml MUST
+   -        be run from the "make" directory.
+   -

+   -   Build the ancillary Ant tasks.
+   -   Generate the Java and C files.
+   -   Compile all sources.
+   -   Create the jogl.jar and platform library.

+   -   javadoc.dev.win32:
+   -   javadoc.dev.x11:
+   -   javadoc.dev.macosx: create the internal developer Javadoc.  This includes the

+   -
+   - Optional properties:
+   -   -Djogl.cg=1 when combined with the build or javadoc targets will cause
+   -   the experimental binding to NVidia's Cg language to be built.
+   -
+   - Thanks to Rob Grzywinski and Artur Biesiadowski for the bulk of the
+   - ANT build, including the GlueGen and StaticGLInfo tasks, the building of
+   - the Java generated sources, the first and second phase Java compiles, and
