(fixed) 2.15 Spearhead server.

[Ryan C. Gordon]

Try this one:
  http://icculus.org/betas/mohaa/spearhead_lnxded_2.15-BETA5.tar.bz2

Should work better. Fixed several strange memory issues (including, I
think, the Event memory pool thing that originally gave me trouble, so
we're not calling malloc() nearly as much. Performance notes are welcome.)

The ZoneID crap should be fixed, too.

I didn't put the .pk3 files in this one, please grab them from beta4 if
you need them.
