TEST: Karma down to IE8 on sauce + expect.js

[ryan-roemer]

• Swap chai for expect.js (consider on func tests too)
• Add sauce integration.
• Have unified coverage go to coveralls.

Just curious about the purpose here – is it to widen our potential failure scenarios, or is there something we can't do with the current test setup?

[ryan-roemer]

I'm testing AMD and RequireJS using Karma for speed because the buildout for functional tests would be huge. The unit tests will be our "many and flexible" tests, the functional tests will be our "ensure the real page scenario works"

Closed in #18 I think – reopen if that's wrong!

Maybe the "down to IE8" part isn't set up yet? /cc @ryan-roemer

@exogen -- Yup! Karma needs some sauce ;)
