function update_settings_submit

Form submission handler for update_settings().

Also invalidates the cache of available updates if the "Check for updates of disabled and uninstalled modules and themes" setting is being changed. The available updates report needs to refetch available update data after this setting changes or it would show misleading things (e.g., listing the disabled projects on the site with the "No available releases found" warning).
