Incorporate automated tests

[averyvery]

With Freebie, I learned messing with EE's URLs is crazy stuff. There are a lot of possible URLs, a lot of extensions and states, and it's impossible to test them all by hand. Fortunately, I wrote a little test suite, but unfortunately, it had a difficult setup and I ended up being the only person using it.

With Freeway, I'm hoping to:

• Have an automated, PHP test suite
• Auto-unit test Freeway methods for dumb errors
• Auto-int test routes and URLs to make sure they perform as expected
• Use a test system that allows devs to easily fork and add failing tests when they find issues
