Refactor notification management

Browse Source 
- centralize the logic for skipping over unwanted notifications
- use *Compat methods wherever possible
- use unique and persistent ID (update notifications)
- switch to using BigText style by default (since we can now update existing notifications)
- for Pebble: delete and reinsert notification as updating is not possible
