Replaced the insecure os.tempnam() with tempfile.mktemp().

Update for the generic_fns.sequence.display() function.

Now the function operates correctly with IO redirection of stdout.

A temporary fix for catching stdout during the execution of all unit tests.

The aim is to eventually have stdout collected for each test run and appended to the failure or
error message if the test was unsuccessful.

Bug fix for running solely the system/functional tests.

The interpeter, which is essential for the tests, is now loaded.

Changed the --unit-test command line option to --unit-tests.

The old option still works thanks to the optparse package.

Added the command line option --system-tests to run solely the relax system/functional tests.

Removed the import of the now non-existant 'Colour' class.
