check status of running status

This adds a better output for some tasks if the broker is not running.
The user gets the information that the broker is currently not running.
Users are confused if they see a java stacktrace on invoking commands -
often they do not read error output in detail.
This change respects that the script can also be used to contact remote
brokers - if ACTIVEMQ_QUEUEMANAGERURL is defined you get the regular
stacktrace, because the script cannot know about the state if a remote
broker.
In >98% of all cases this script controls local instances - we should
help the common user!
