Updating the Session Key in the Other Settings form causes unexpected User Interface issues

The Actions button on the Other Settings form has an "Update Session Key" action.

If the Session Key is regenerated, allow Web Services session, including the signed in web administration session become invalid upon saving the settings.

This could have an unexpected effect on the User Interface, e.g., error notifications popping up.

Now, if the Session Key has been updated, upon saving, the web administrator is returned to the login form.
