More key view loop madness

- It turns out Cocoa DOES recalculate the loop when calling recalculateKeyViewLoop. It does not wait until selectNext/PreviousKeyView is called.
- Cocoa calculates the key view loop for nibs that do not have one, but does not call recalculateKeyViewLoop.
- If there is no first responder and no initial first responder when a window first becomes key, use the first valid key view, not the first geometric key view.
- Made allViews function a method, not sure why it was a function.
- Unit tests now pass.
