Add Unix jconsole launch scripts to the AS7 distribution.

Launching jconsole with remoting-jmx requires additional jars to be on the classpath (see the jconsole.sh in the remoting-jmx project).

So that AS7 users don't need to manually set this up we should provide a .sh and a .bat with the correct classpath in the AS7 distribution to launch jconsole (Will require JAVA_HOME has been set) - if there is any way we can get this launch to use jboss-modules that would be even better so we don't need the versions of the jars within the scripts or a way to generate the scripts based on the versions but that may be too much for now.
