Updated Testing and added pics of code coverage

Testing now has 99.1% code coverage (because the Testing class itself is
never called). The Property and Player class get 100% coverage.
Changed the way Property and Player call their initialization (no change
to code usage needed).
Changed when rentArray and upgradeCostArray don't fit the bounds in
Property it gets the original setting of both arrays, instead of setting
it to null. **MAY REQUIRE CODE CHANGE FOR MATT AND BRIAN**
