[product: zaphod][project: zaphod-v0.3]: run-tests processes command line.

SYNOPSIS
[modified]m42/test/all_tests.py: Implemented run()
[modified]m42/test/run-tests: Replace test invocation with all_tests.run()

DETAILS
This allows run-tests to process command line parameters and test
configuration file directives before running all the tests. This allows
easy reconfiguration of download info and other parameters through
a config file change, making regression testing easy.
