Feats generator done!

* Completed the feats generator
* Finished racial bonuses for armor class generator
* Deleted the racial feats table and tests, as they are no longer needed
(thanks the the racial feat selections)
* Refactored stress tests so that a class will implement a stress test,
instead of inheriting the test and losing the context
Clean up, clean up...

* Added lightfoot halfling skill adjustments table
* Remove unused poor base attack group from class name groups
* Added land speeds table
* Fixed no-longer-applicable/correct tests
* Reverted AssertIterations back to how it was before
* Had class name randomizers also implement the stress test
individually, instead of in an abstract class
* Created table tests class, from which all table tests inherit the
table name property
