[desktop] Calendar page

[Gunnar Hjalmarsson]

It would be great if somebody could volunteer to rewrite the
clock-calendar.page, so it refers to the Calendar application (terminal
command: gnome-calendar) instead of Evolution.

Current wording:
https://help.ubuntu.com/stable/ubuntu-help/clock-calendar.html

Unlike Evolution, Calendar is installed by default in Ubuntu 16.04.

Calendar is automatically integrated with the clock, meaning that up to
5 of the coming events during the next 4 weeks appear below the calendar
when you click on the clock.

Please note that this is a last minute request. To be useful it needs to
be done today (March 17) by 20:00 UTC...
