Reduce all scripts to one

Now there's only one script used to take the maps from their raw, exported
state from R and turn them into the maps needed for the atlas. The script is
publish_map.py and is run with the following syntax:

python publish_map.py map.html

To do an entire folder in Linux:
for f in *; do python path/to/publish_map.py "$f"; done
In Windows (untested):
for /r %i in (*) do python path/to/publish_map.py "%i"
