Resubmitted two bug fixes from before poison tree fiasco. One issue with strongly typed navigation where BaseUrl was null because coming from old IISExpressRunner class. Two AppConfigurator was throwing an exception on basic usage. Wrote a failing test before fixing this but problematic as fires up web browser. Need to look at testability of configuration
Added BDDfy/AutoSubstitute tests and converted Franck Theolade's IWebElement tests into that format as examples
Fixed up the NSubstitute reference
