Docker Volume Support and Remove the Last of the Files (Last Docker PR I Promise)

[colin99d]

Description

Adds documentation so that users can easily create volumes for their docker stuff. Also @Chavithra is a big fan of deleting unused files, so I deleted some. If anyone wants them they will be in the git history FOREVER.
