Tests don't pass

[TehShrike]

To reproduce:

git clone https://github.com/browserstack/browserstack-runner.git
cd browserstack-runner
npm install
npm test

Output is:

Using config: /Users/josh/code/browserstack-runner/browserstack.json
Configuration file `browserstack.json` is missing.

atm, testing involves pulling sample repos with test cases and running tests against them.

git submodule update --init --recursive

Sample browserstack.json:

{
  "username": "BROWSERSTACK_USERNAME",
  "key": "BROWSERSTACK_KEY",
  "test_path": "tests/external-repos/<sample-repo-name-here>/test/test.html",
  "debug": true,
  "browsers": [
     "chrome_latest",
     "firefox_latest",
     "ie_11",
     ...
  ]
}

We do need better test coverage and an easier way to test. Ideas are most welcome.
