add-user utility reports "No java.io.Console available to interact with user." when used silently with su and piped to a file.

./add-user.sh from a script does not work anymore. In previous versions it worked. It has to do with the "theConsole" object being null.

In the same breadth, the --silent=true option in add-user.sh does not work anymore. Again has to do with the need for "theConsole" object being null.

The --silent=true option was added because in some environments, System.console() returns null[for example when the Izpack installer calls that script] and the add-user.sh script breaks because of its dependence on System.console() object to print stuff.

This is using a build (jboss-as-7.2.0.Alpha1-SNAPSHOT) of master from today:

[tom@tomsfc16 bin]$ sudo ./add-user.sh --silent=true foo bar > /tmp/capture.log 2>&1
[tom@tomsfc16 bin]$ cat /tmp/capture.log
Exception in thread "main" java.lang.IllegalStateException: JBAS015232: No java.io.Console available to interact with user.
