[flexcoders] Passing data from TitleWindow to application

[jmfillman]

I've attempted to model this after an Adobe example found here: 

http://livedocs.adobe.com/flex/201/html/textcontrols_060_19.html

I'm trying to take that example and apply it to set the height of a 
control, based on logic in the TitleWindow popup. When you close the 
TitleWindow, I want the height value of the List to be updated.
