[rules-dev] KnowlegeAgent Tests

The KnowlegeAgent tests have been fragile for a while, related to "wait" code and file issues, particularly on windows. Something has changed recently and now they aren't working on the linux hudson server either. So I'm now in the process of refactoring the tests to make them more robust, and they will hopefully run faster too, as I'll use call backs when something has finished instead of waiting for X seconds in the hope that something has finished.
