Improve testsuite
added testsuite

This testsuite helps to ensure the proper operation of the unix init
script on various unix platforms (Linux, OSX, ...)
check for local running broker, testing improvment

Prevous releases checked for a local running broker but missed that this
tool is also usable to connect to remote brokers for options like
query, bstat, dstat, purge and browse.
The new behavior is different: If the script uses the '--jmxurl' or
'--amqurl' from the configuration file (i.e. 'env') it checks that the
local broker is running. If the '--jmxurl' or '--amqurl' is specified as
an commandline option the check is not performed.

The previous change alos resulted in a different behavior for the
testcases. The testsuite can now be executed successfully on Ubuntu
14.04 (which uses /bin/dsh) and OSX.
