Add option for PID file
Add JVM arg for PID file and runwar will write the file. Once this is in place, I'd like to see about it using it for a smarter server status check.
While refactoring, we also moved the tray options and predicate files into the custom server directory for WAR servers as well.
we found in last mondays investigation that in the runwar project, in Server.java file, line 670, the code is generating a file with the already. so now we can try and use this in a smarter server status check.
