[msm-notifier] : Notifications settings can't work

Created by: scachemaille

If we set/change the notifications settings in manjaro-settings-mananger, msm_notifier don't know about these changes and will always use the default one. As manjaro-settings-manager is launched as root the saved settings are in root home directory but the notifier run as user and don't use the saved settings. the best solution would be to remove notification settings editor from the manager and add it in the notifier.
