XMLRPC::new2 takes a string in older rubies
Pick up changes from master branch
Changed the SoftLayer Resource mechanism so that it uses a predicate block to determine when a resource should be updated.  That way, if developers want to provide different mechanisms for determining when to update a model, they may do so
Added Object Filters to the basic set of API parameters.  The current filter behavior is based off of information found in Python, but may need to be validated against IMS more carefully
