Link to Map

[Zykino]

In each event, there is a field for the Location.
It would be nice to have a link to the Map application / external map (OSM / GoogleMap / ...)

An alternative is to have an overview of the map IN the calendar instead of completely going outside. (I have no preference between the two : both have pro and cons.)

As a plus, if cozy/cozy-registry#29 is implemented at the time this enhancement is treated you could auto-select between Map app or external depending on the user's installation.
