Fix mistake in unity selftest without output spy running.
Namespace self-tests for consistency across ThrowTheSwitch projects (like being able to test:all)
Reduce clutter of NAMED self-tests in task list.
This resolves#219. When generating a new module, if all the files to
generate already exist then it fails as before. If some of the files
already exist, then the files that need to be created are created. Any
existing files are not changed.
Also added a bunch of tests for this feature via rspec. Run them from
the test folder with `rake spec`.
- Modified rakefile to look in correct directory for script unit tests
- Updated paths in script unit tests
- Updated 'expectdata' files to match latest version of generated code
- Fixed bug which prevented generate_test_runner from loading config from
yaml file.
