Dockerfile to run in docker

[ShaneMcC]

This should fix issue #6

Realistically, users are going to want to use docker-compose or so to actually run this and make it work and have mysql dbs etc, and it would be nice to put an example somewhere.

This doesn't have an alias for the resources, so won't be quite right yet

Not issue 2 :)

Includes AliasMatch stuff now, and also appropriate config to make /conspectus/themes web-accessible.

Some quick testing instructions to help you:

# Run a throw-away database container (when you ctrl-c this it will vanish along with all the data)
docker run --name conspectus_db -e MYSQL_USER=assets -e MYSQL_PASSWORD=asdfsdf -e MYSQL_DATABASE=asset_tracker -e MYSQL_RANDOM_ROOT_PASSWORD=true --rm mysql:latest
# Watch and wait for that to be ready: [Server] /usr/sbin/mysqld: ready for connections

# Build the container
docker build --rm -t conspectus .

# Run the container
docker run --link conspectus_db -e SQL_HOSTNAME=conspectus_db --name conspectus_web -p 800:80 --rm conspectus

# Test at http://localhost:800/
