Nonblocking check for dialog results

[GoogleCodeExporter]

Add a non-blocking function in the UiFacade to check if the current dialog has 
a result.

Currently the only way to access the dialog result is to call 
dialogGetResponse(), which blocks until the user closes the dialog.

It looks like the only source code changes would be to give FutureActivityTask 
an isDone() function that returns mResult.isDone(), and then a 
dialogHasResponse() or dialogPollResponse() or some such would call 
mDialogTask.isDone() to check if the dialog has finished.
