Need Integration Tests

[ifandelse]

Our specs should include an integration test where:

• test runner (parent) has two iframes (child 1, child 2) in the document
• parent and children need to federate
• parent should:
  • broadcast an identical message to both children that both children are configured to listen for via the filters
  • broadcast a message that only child 1 will receive
  • broadcast a message that only child 2 will receive
• the children should reply to the above messages on a different channel/topic to which the parent is listening.
• when the parent receives the replies, the tests pass
• this should be using mocha/should/expect

I don't have a problem with this activity running the main test runner under a top level describe indicating it's an integration test, etc., but am also open to it running in a separate integration.html test runner...

Now that web worker support has landed in v0.2.4, we need an integration test for that as well...
