Species Navigation Improvements

The improvements to navigation for the species section I referred to in my last update are now up and running; you can see the form at the bottom of every species, state and province page in that section. No doubt still a few bugs to work out, but it seems to work well so far.

Other recent changes include minor fixes to the individual article/update/news item pages and to the article archives. The font size has been made a little smaller, which might help those with lower-resolution screens.
