Get namespace before passing off to NativeExec
CommandFactory.CreateByServiceName takes new optional string value which can be the fully qualified class name, or just an alias class name to prevent ambiguity
added Namespace string property, used by CommandFactory to create the command.
One more case : default classpath + command alias, ex Console=>WPCordovaClassLib.Cordova.Commands + 'DebugConsole'
Config handler has to treat the xml 'name' as a key but use the wp-package param value
Apply the same changes to wp7
