Learn from events for current week

[maxpatiiuk]

Look at what events there are this week and what calendars they fall into and provide autocomplete predictions based on those
Or, more formally: If creating a new event for the week, and call it "A", and there is already event called "A" this week, and it's in the calendar "B", then if there is no autocompletion rule that says which calendar "A" should go into, it should go into the "B" calendar

Should be implemented by fetching data from API, or by scrapping the webpage
If scrapping the webpage, that would make #76 more feasible too
