Added more to the British Pharmaceutical Codex.

Yesterday, I added a few dozen more preparations to the BPC 1911; I've lost track of where I left things last time, so I don't know how many more .html pages that is.

With that update comes a plant name database update: about 150 more latin names (including about 25 synonyms), about 270 more URLs, about 600 more common names, and a few corrections.

About that database update: I've added most of the single plant-related blog posts to the URLs in the plant name search. Whee!
