wrong test
better return values and some documentation
#30 Write correct unit test for LeMike_DevMode_Model_Core_Email_Template::send

- Make a fixture with the option lemike_devmode_core/email/active disabled (0)
- Test/Assert that fixture
- Mock the Mail-Template so that it only outputs a unique string (in the usual way with $foo->getMock() etc.)
- Test/Assert that mock / mocking the according method
- Dispatch newsletter/subscriber/new with the post ['email' => 'lemike_devmode']
- Test if / Assert that the dispatch was successful
- Fetch the output
- Test against / Assert the previous defined unique string
- check if magento output is supressed by testing helper and current response body
