Title: Lost taxa are now stored with the "lost_species_tree_node_id" tags

In e74, we changed the way the information about lost taxa is stored in the gene trees

If you click on the blue squares off the collapsed the nodes ("Old World rodents: 2 homologs", "Laurasiatherian mammals: 12 homologs", etc), you'll see that the "Lost taxa" entry is not shown on the zmenus of the live site
