Initial work on Docker Build process

`/opt/uwsgi.ini` was where I had planned to put the main Django app wsgi file. The second one (`/opt/security-updates.ini`) was a cron-style security update script running under uwsgi's `unique-cron` option. It just runs the following:

*/opt/security-updates.ini*
``
[uwsgi]
unique-cron=0 0 -1 -1 -1 grep security /etc/apt/sources.list > /etc/apt/security.sources.list && apt-get upgrade -y -o Dir::Etc::SourceList=/etc/apt/security.sources.list
``
