Fixed All Memory Leaks

**Needs Thorough Review**

See `-[CDRSpy release]` it's a mess. I couldn't find a good refactor - moving parallel retain counting to `CDRSpyInfo` causes crashes. Relying on `-[retainCount]` is pretty far up the list of evil things. I guess this makes spies more evil than they already are.

I've also added CDRSpy specs into the OCUnitAppTests bundle so travis can pickup ARC-related failures.

Most of the leaks were from earlier PRs of mine where I forgot that ARC isn't default in cedar.

PR #164 is blocked by this.
