Fixing WPSconfig if cannot find native2ascii

This really only applies to older versions of WebSphere Portal (pre 6.1, as I believe it uses ConfigEngine now), but I've encountered this a couple times for a variety of reasons:

Executing native2ascii with native encoding 'UTF-8': wpconfig.properties -> wpconfig_ascii.properties

Just add the following to the classpath portion of the command at the bottom of the WPSconfig.sh or WPSconfig.bat file:

$JAVA_HOME/lib/tools.jar

The jar tools.jar is missing from the classpath apparently, or buried too far down, and the script is dependent on this to create the OS specific properties file to run the task.
