Node Orienation - //TODO's indicate suspicious code

Suspicious Code:

- look for //TODO's in the code
- the code that positions a stage (popup or regular) is suspicious and contains instanceof
- table has some arrow key behavior that is not accounted for and appropriately flipped
- text field skin getAlignment() may not account for all alignment combinations that can occur

Possible bug: TextArea creates Text nodes based on the current effective orientation. If that changes, the Text nodes are not updated (need to write a test case to prove this).
