text: Title: Do not split digest emails, summarize instead
  Body: ### Describe the problem
  
  This morning I woke up to 79 emails from Weblate in my inbox. All sent within the span of two minutes, all notifying about a single project (Organic Maps).
  
  I checked my preferences. They correctly say that I want to receive digests, not one email per message.
  
  However, it seems like even though I have set my preferences like this, if there are more than so many notifications of the same type (a 100?), the notification system will split them into multiple digests and send them as multiple emails. This seems rather suboptimal.
  
  ### Describe the solution you would like
  
  Instead of sending dozens of emails, send just one, but add a note mentioning that "there are more changes than we have included here". Getting dozens of emails about new strings/suggestions/etc. isn't any more helpful than getting just one email. It's counter-productive even.
