Notification Filtering (IOS-241) (#1319)

- Adds a new cell on the "Everything"-notification-screen to show
unwanted notifications
- Users can define what "unwanted" means to them using the new
"Filter"-button in the upper right corner of the Notification-screen
- Filtered notifications are sorted by account and users can
dismiss/accept if they want to get notifications of that user (it's some
standard table-views and delegates)
