Refactor notifications work to use 1 interface for writing notifs & use dates

Summary of changes:
1. Always use the sxmo_notificationwrite.sh script to write notifications
   rather then sometimes using echo to the DIR
2. Reorder args for notiffile spec to be action as 1st line, watchfile 2nd, and
   rest as msg; this way msg can be multiple lines without propogating bugs
3. Write calls as a standard notification via sxmo_notificationwrite.sh
4. Use datestamps from notification files instead of filename, this way (3)
   works without extra logic
5. Various style fixes
