Description

Steps to reproduce:
1. Create a custom TitleBar skin, making sure to not include a titleText.
2. Create a TitleBar in your application, applying the skin.
3. Set a title on the TitleBar

Actual Results:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Expected Results:
Since titleText is optional, it should just not do anything with the title if it's set and no skin part exists.

Workaround (if any):
Put a titleText in your skin and set its visibility to false.
