APNSNotification always contains "aps" keys - it should be added only if is not empty

[GoogleCodeExporter]

When building an APNSNotification, an "aps" key is always appended

--> keys.append('"aps":{%s}' % ",".join(apsKeys))

Even if the apsKeys dict is empty.

This is an error, the dict should be checked and only if is not empty it should 
be added.

The reason is that some services in the Iphone expect an empty notification 
with properties only and the 'aps' key causes an error.

APNSWrapper version - 0.6.1
