Candidate 0.16 release.

[Brendan Burns]

Hey folks,
after far too long, I've got a 0.16 release put together.  It includes 
a number of nice fixes including:

Load more pakfiles [Toni Spets]
Load bigger PCX images [Toni Spets]
Railgun easter egg bug fixed [Nick Warne]
Preliminary x86_64 support [Nicolas Regnault]
Red/Blue 3D support <http://www.jfedor.org>
Retexturing support (thanks to Karen Pouelle)
Better FreeBSD support (thanks to /danfe)
Advanced Joystick Support
Some miscelaneous fixes which I've forgotten about

Its at:  http://www.icculus.org/quake2/files/quake2-r0.16.tgz

If some people could download it and try it, that'd be great.

Also, for those of you who are interested.  The mouse bugs on the head 
of CVS should be fixed too.

Thanks for your patience and testing.
