Schedule entries now filtered by year

We've just updated the schedule page to filter entries by year instead of by month. Filtering by month was a little too granular, and practically it's more useful to see a schedule for an entire year than just for a month.

However, to keep things organized, we're still grouping entries by month within the year view, making it easy to still see all the entries for a specific month if you need to.

One nice benefit of this change is that you can now export all the entries for a specific year at once, which was previously not possible.

And, like before, when you first go to a schedule you'll only see upcoming entries by default.
