Auto build for sale posts for posters from ExpressoBeans.

"""Auto build for sale posts for posters from ExpressoBeans.

Save your Trades page as an HTML file, and put the file location
you saved it at in FILE_PATH below. Right now this will only work on one
page of trades, so if you're selling a billion items this won't
work for you.

At the bottom of the script, put markdown(), facebook() or bbcode()
depending on where you are posting the posters.

Python 2.7, although I ran into enough unicode BS that I _almost_
wished I coded it in 3.
