Changes

Make Eclipse build correctly

Removed the Java builder, since it was rebuilding stuff the Ant build
had already done. Turned on the Ant build for incremental builds.
Changed the classpath of com/jogamp/opengl/impl/gl2/fixme/ to
jogamp/opengl/gl2/fixme/ to reflect the recent move.

Fix path to FixedFuncHook.class.

The path to FixedFuncHook.class didn't get changed in the recent
package move, which made the dependency checking wrong in
the java.generate.composable.pipeline.custom.check.glfixfunc
target.

Prevent native libraries from always rebuilding and stripping

The cc task will always re-link, even if no source files are built.
This commit wraps an uptodate task around cc to prevent this, so
the libraries will only be rebuilt now if a source file changes.

This commit also moves library symbol stripping into the same
uptodate task, so it only happens if a library is built (previously
the libraries were always stripped).

Add new all.ide target for use in Eclipse, NetBeans, and IntelliJ

The new target just omits final JAR creation and file copying for
extra speed within an IDE. We also change where Eclipse looks for
the native libraries, since this new target doesn't copy them
to jogl/build/lib.
