Topic/pep8 cleanup
Update supervisorctl config to use gunicorn

Use new project directory (/usr/local). Use better log files. Use the
vegphilly user instead of the vagrant user. rename job to just
vegphilly.

Add nginx. Fix and implement nginx config.

Make build use nginx and gunicorn.

Add dummy log config to satisfy gunicorn.
Make postgres/app use vegphilly user, not vagrant
Update README to point to new log file
Update fabfile to use new tooling

New supervisor job, new log files, new project root dir.
Update vagrantfile to share new project root
Update build script to use new logfiles
Add fab task for running backups on remote server
Factor out db_backup tools for fabric and cron

The logic for running remote backups is not located in a db_backup
file that can be used as a script for a cronjob. The fabric file
imports these functions to remain DRY.

Added an __init__.py file so that the fabfile could find the db_backup
module
Add cronjob for backups

Partially fixes #193 on github. Partially because we are in the
process of merging out build tools to work on both dev and production
servers. In the meantime, someone needs to remember to run these
commands piecemeal on the production site to get the cronjob working.
Merge pull request #265 from steventlamb/topic/ops_updates

Topic/ops updates
Have gunicorn use 12000, not clash with runserver
utf8 encode some fields to enable csv support
Modify backup_db fab task to transfer files too
Make gunicorn use a separate logfile

Necessary for debugging the ever-changing build config
Update nginx config to pass more to the app

This fixes a weird problem where some parts of the site were
forwarding to a bogus hostname.

For example hitting localhost:8080/admin/ would work, but
localhost:8080/admin would forward to localhost/admin.
