Fixes #12
Current fix for saving time created as given by a webservice call to UBItem|UBMessage::create with a property value for time_created.
It is a "double save". Thus it is a naughty fix, but one that doesn't touch Elgg API.
Merge of Pebls and my changes
Adapting descendants of UBItem to new save() signature due to issue #11 and its fix.
