Add SLChangeUserInfoSucceeded for ILLiad patron information webpages
This option exists for Ares but is not available in ILLiad 9.1
The currently available webpages allow users to update address information and other personal account details, but there is no mechanism for letting a user know that their update has been successfully submitted-- i.e. the page reloads, displaying the information a user has just entered into the available fields, so from the user perspective there has not been any apparent change.
A customer also brought up the scenario where they would like similar functionality when creating a user. They would like the user to know when their account has been successfully created.
