Moved GlueGen out of the JOGL workspace and into its own project.

Restructured JOGL and JOAL build processes to separately invoke
GlueGen's main build.xml before using it to generate their code.
Refactored OS/CPU detection code into gluegen-cpptasks.xml build file
in GlueGen workspace, which is now imported by both the JOGL and JOAL
build processes. Unfortunately it seems to be somewhat difficult to
completely factor out the C compiler configuration into the GlueGen
workspace so this has been left for a later date. Added missed
ALProcAddressLookup file to JOAL workspace. Updated JOGL and JOAL
build documentation. More documentation for the GlueGen workspace is
forthcoming.
