 I couldn't find a proper way how to hook into WP after updating/saving the
 settings page option. For example: I have a custom settings page built
 with register_setting() function and I want to call a custom function once
 the settings page option has been updated, but there's no action. I think
 it would be very useful to have this hook.

 In my patch, the 'settings_updated' action is triggered right after the
 settings page option has been updated.
