Restructure automated testing

[samsmithnz]

There are too many integration tests, and not enough unit tests

goals:

1. Write more unit tests and refactor integration tests to have less
2. Refactor each of the major sections. Focus on Steam and WorldCup first - these tests currently take the longest to run.

• Guitar Tab
• World Cup
• Foo Fighters
• ITunes
• M&M's
• Steam
