A quick selftest running non-GUI after a jenkins build

to start:
    sh run.sh

or
    run.bat (windows)

executes the tests found in ~/stx/goodies/regression/*
and generates a junit-xml compatible output file 'testresult.xml',
(to be consumed by jenkins).

the cmd script will start stx with Start.st
Start.st will prepare the stx environment required for the unit test.
For e.g. loading required packages.

The last command of Start.st will file in RunUnitTest.st class and send #run.
The RunUnitTest class will perform all (or a subset when use the --runOnlyExpeccoUnitTests paramter) unit tests
and create the report file ""
