Changed the way the new property is being set.  Instead of listening for a bunch of existing properties (that's bad), hooked up directly into `LabeledSkinBase.updateDisplayedText()` which does the actual manipulation with the text.

In addition, modified the Monkey Tester
https://github.com/andy-goryachev-oracle/MonkeyTest

to add ability to see the value of various properties in real time.

For example, to verify that the new property is being updated in the context of a table, select TableView page, set Control -> Context Menu -> Show Properties Monitor, select a cell and right click to open the Property Monitor window.  Find a `TextFieldTableCell` in the list and observe the value changing when resizing the column:
