Complex test cases implemented using the OOoRunner by default use a connection
string of
  socket,host=localhost,port=1200
as specified in qadevOOo/runner/lib/TestParameters.java.

However, if this default doesn't work for whatever reason (for instance, because
another user on the same machine is already using this port), then you need to
override this. The current ways to do so all require changes of source code: You
can either re-compile the runner with a modified connection string, or
re-compile your test cases (there can be a lot of them when you do the
pre-ready-for-QA-tests of a CWS!) to modify the test parameters at runtime.

Both solutions are not really satisfying, especially when you have to run a
large number of tests in the pre-ready-for-QA phase of a CWS.

It would me much more convenient if the parameters could be specified
dynamically, e.g. via a dedicated properties file (shared by all tests!), or via
environment variables.
