Fixing up the database import process

[seanastephens]

If you run db_setup.py now, the script will

• pull the lastest data
• format it for the db
• log the rows it can't convert
• produce a list of column headers

Additionally, the python script was refactored so that it will be a lot easier to add, for example, nicer header names for all the columns.

There are a bunch of small changes, but nothing to any javascript files.

One issue - the script now has some dependencies. Whats the best way to make sure that the machine it is running on has all of

• python
• pyproj
• dos2unix

python is a gimme, but the other two are definitely not.

EDIT: Later commits address this.

you can use pip to install python dependencies and export that list to a requirements.txt file.

so you'd use pip to install the dependencies, then run pip freeze > requirements.txt to save them to a file. then once you push that file we'd run pip install -r requirements.txt
