Changes:
* SprinklerTest: TestRunner is now stateful. The factory method NewInstance() has been added. This addresses the need to hold the instances of the single tests because these sometimes depend on each other.
* TestSets renamed to TestSet
* TestSet.GetModules() returns now a List instead of a Dictionary. The modules are sorted by test-code within each group.
* RequestFormatTest: non-unique ID "TR01" renamed to "CT05"
added ignore patterns
