The refactor never ends

* Moved having wings and size to the race object. Need to add tests and
such to race generator
* Refactor skills generator for readability
* Get racial and monster skill tests to pass
* Refactor hit points generator to use groups instead of switch
statements
* Should make class name groups for alignments, for the class name
randomizers, to help eliminate those switch statements as well
* Improved race generator stress tests
* Also need to go and get places that are referencing the collections of
race sizes and use the race property instead
