allow timeout parameter to be specified on a per individual test basis

[bxparks]

TestRunner has a global timeout.
It's easy enough to implement a timeout per-test, at the cost of one extra byte per test(), testing(), testF() and testingF().

I'm going to be realistic and say that this will never get done. People haven't expressed any desire for this feature, and I will never use it, and it will never rise high enough in priority. Closing.
