adding Dockerfile to make deployment easier

[kmjones1979]

I had some issues with the install using the script and didn't want to spin up an Ubuntu virtual machine so decided to convert it into a Dockerfile, hopefully someone else finds it useful. cheers!

nice, i was just considering to make that.
maybe adding some doc to the readme on how to run it would make sense.
for anyone coming across this in the meantime:
docker build -t bbht-docker:latest .
docker run -p 80:80 --rm -ti bbht-docker:latest
and then you can browse to localhost:80

@nahamsec This has been open for a while and seems like a sane option, maybe you could take a look
