Display location of appointments

[redcatbear]

Is your feature request related to a problem? Please describe.
Planify shows today's appointments in the "today" view on Gnome, which is very helpful in combination with the tasks.

It would be very nice if the location was visible to (e.g. in a detail view). Ideally, if the location is a link, it should be clickable.

Describe the solution you'd like

• Auto-expand an appointment like the task when the user clicks it.
• Display location
• Make links clickable

Describe alternatives you've considered
Alternative A: Click on the appointments and open standard calendar application
Alternative B: Hover text with location
