Create Notification with create state

When new content is created and the state changes from creation state to another state it was impossible to trigger a notification. I have added a new hook, insert, which allows to notify an event not when workflow is updated but also when a new content has been just created. I have also modify workflow module to allow from workflow Notification form to include new trigger when state goes from Creation to any other state. I have also corrected mistypo in a file. I attach here the patch for both files. For more info contact me.
