References for localities

Localities assigned (and mapped) to species in their profiles now show the reference that we use for the assignment, be a picture at the locality, a video, a reference, or a museum collection record. In this way, we can improve the soundness of the data. In a similar way, the localities profiles show an option to list the species by reference, which in the same manner shows the references for the assignment of a species to the given locality (Juan Miguel Artigas Azas).
