Integrate "Running IDs" into Quilla

[cryptaliagy]

It would be beneficial for Quilla to have a "running ID" to uniquely differentiate between runs.

Some care will have to be taken to implement the running IDs in a way that allows multiple quilla tests to be categorized as part of the same "run", since if it were just added to the context and every time the context gets created a new running ID gets generated it would mean that each Quilla test would have a different run ID even though they could be executed as part of the same test suite
