The twiddle.sh script should read environment variables from run.conf in the same way as the startup and shutdown scripts do - e.g. JAVA_HOME and JAVA.

Additionally twiddle.sh should honous the JAVA environment variable instead of overwriting it with $JAVA_HOME/bin/java or "java". This makes it consistent with startup and shutdown which do honour JAVA.

Finally the header should be changed from JBoss Shutdown script to JBoss twiddle script
