Adding a wsdl_path configuration variable so that the parent application can optionally cache the wsdl file they want to use in order to avoid making a web request every time
Updating AriaApi::Service to use the wsdl_path configuration to optionally load a local wsdl file in order to avoid making a web request
Uses method missing to lazily define class methods for the wsdl actions so that they aren't defined before the AriaApi::Configuration variables are set by the parent application
