Updated to use Go 1.11.2.
Fixed Docker ENTRYPOINT and CMD.
Changes to the Dockerfile are the reason for the minor version revision. If the container was started with an explicit:
docker run ... halverneus/static-file-server /server
simply remove the explicit call to the executable:
docker run ... halverneus/static-file-server
This 'bug' was fixed to match the behavior of the existing README.md documentation.
