Mostly bugfixes and some minor improvements. When validating objects, the errors attribute is automatically updated with possible validation errors. When non-existing or invalid states are called, an error message is shown instead of a blank screen. URLs with existing query parameters are now parsed correctly by the IsmoURL class.
Creating XML-RPC services is now easy with the included IsmoXMLRPCState class. The unit tests have been changed to use PEAR's PHPUnit package. Some string optimizations were done, and a couple of bugs were corrected.
IsmoCore now supports both a query parameter based URL style and a path-info parameter based one. A bug related to session propagation when using the path-info URL style if cookies were disabled in the browser has been fixed. The IsmoConfig class has been removed, and the logging support redone and improved.
Ismo's database solution is now separated into its own package. The error handling now honors the error_reporting() setting, IsmoObject got a neat constructor, and the validation system was improved. Authorization can now be done at an action method level in the IsmoState class with the newly-added authorize() method.
