RedHat init script

[Paul Holcomb]

I made a quick init script the other day to start and stop the bf1942
server automatically at boot and to provide an easy way to restart the
server when changes were made.  And since I saw a number of posts
about how to start the server and about nice'ing it afterwords I
thought I'd sent it out.

Things to keep in mind:

-the scripts expects to run as user "bf1942".  If you don't have such
 a user, create one.
-the script expects the game to be run from
 /bf1942/bf1942-lnxded-1.2beta1, but this location as well as the
 where the log goes to are easily changed by editing the variables at
 the top of the file.
-all arguments passed to the server go in /etc/sysconfig/bf1942 in the
 $ARGS variable.
 (e.g. ARGS="+game Desert_Combat" could be such a line)
-I didn't spend a lot of time on it, so its not perfect, but it does
 work for me.
