Species list – more filters

I’ve made some minor changes to the species list. The column that displays the class, order and family to which a species belongs now renders the taxonomic groupings as hyperlinks, so it’s now possible to immediately jump to all other species within that grouping. Secondly, the ‘current list’ text above the list now more accurately represents the list beneath it, in that if the list is actually the result of a search, this will now be stated.
