Allow to control the interactive flag from the layer

This flag deactivate all interactions for a path. It can be useful
when some polygon is used to delimitate an area on the map, but
when we don't want this area to be clickable.

I've a case where I've many of those polygons in a given map, and
they are imported, so I don't want to go one by one to deactivate it.
