Declaring tests as an object

See issue: https://github.com/spacejamio/meteor-munit/issues/4#issuecomment-47564140

This allows for really clean declarations within coffeescript, like this:

    tests:
      myTest1: (test) -> # Name parsed to "My Test 1"
      myTest2:
        skip: true
        func: (test) -> # Name parsed to "My Test 2"
