Confusing word between group activities (timeline) and activities (long events) :
The new "long event" concept is translated by activity.
But "activity" is a concept already used in Mobilizon.
http://localhost:4000/@groupe_1 http://localhost:4000/@groupe_1/timeline
In code it is "long events" and "timeline".
Suggestion :
- rename timeline to en:"History", fr:"Historique"
