Request for onSettingsSaved event in server.js

Like onAppInstall and onAppUninstall, if you could provide an onSettingsSaved event, it could be used effectively.

Here’s my use-case:

On App Install, I create a recurring schedule.
On every subsequent “save” app settings, I need to delete the old recurring schedule and create a new one.
Because onSave is when I get the timezone information.
