Update

-More icons from Jamie
-Adjust species view canvas more to the left
-Species list in species view is now removed from container div (instead
of hidden) when leaving the view
-Implemented simplified user annotation
-Enabled switching to Species view / Plant selector by clicking on icon
-Enabled changing Chromosome view / Gene Selector icon to green when
entering the view
-Moved border on canvas to its container to eliminate position offsets
introduced by border, when adding child elements to the container
-Changed transition target from All to transform, to avoid transition
taking effect upon changes to visibility attribute (and perhaps other
unforeseen style changes)
