Linux Acedb data update

[Jeff Bryer]

I have updated our Linux Acedb archive with the latest 
data release (2-18).  The archive is ~50MBs compressed and
~141MBs uncompresed.  

If you are just starting out with Acedb on Linux and don't want
to spend a couple hours adding in all 18 data releases, then
this archive is all you need.

The archive is available on trog.mbb.sfu.ca (142.58.213.33) in
/pub/acedb as linux_2.18.tar.Z
