Minor faceOut Update

As reported by Dave Sussman (and others), the initial version expected to be running on US systems (thanks to some hard-coded US date formats in the sample XML data).  I've since updated faceOut to handle those peculiarities (including forcing use of the USD ($) while respecting other locale settings) and added a little "about" popup.

Nothing major at this point, but I wanted to let folks know in case they've run into that issue.
