[Feature | API] Add an activity stream to the API
Created by: valeriomazzeo
Exactly the same set of information that you can see on the home page (dashboard).
At the moment a subset of those information can be retrieved from the atom feed, but they are incomplete and a client needs to implement also an xml parser to get them.
In addition to this, they are also outside the scope of the api path (ex. /api/v3/) and this start to mess things if a client is trying to adopt a baseURL connection system.
