Changing console message when test suite is running

The current console message when a test suite is starting is a bit node-esque. Referring to the test suite as a module doesn't really give it any context in the testing world. The words 'test suite' make more sense in this context. I also changed the color to be a bit more noticeable. 

Supports camel case, underscore format, and dot format module names.
