Got shake event manager limping along

Not sure about the ALPHA value but it seems to trigger when shaken.  Now
I just need to get all of this to work asynchronously.  Pretty sure this
is why refresh doesn't work.
got all parts working but not asynchronously

Coded up a loader for the xml data but now I'm not loading any xml data.
Code was working before but calls in serial were having problems with
race conditions when it was time to refresh the list view so I started
working on the XMLDataLoader class.
