please test the Subsurface 4.0 binaries uploaded to the website

[Dirk Hohndel]

You can find them in

http://subsurface.hohndel.org/downloads

The Mac DMG should now be signed.

Both binaries have received some testing here (e.g. I made sure that
they can open the user manual, an XML files, etc), but I think a bit
more testing by others would be very helpful. I'm willing to redo the
binaries if something catastrophic is wrong... but I'm really hoping to
get the release out in the next few hours.

Thanks for all your help
