Start data store properly (fixes #21)

[tpetricek]

• I had this problem: Docker-compose up failing because "port is already allocated" docker/compose#4950 and so I changed the ports from 8080:8080 to just 8080 as recommended there, which worked.
• We had outdated version of paket.bootstrapper.exe which was preventing package restore
• We have to include paket.lock (it specifies the versions of packages to download)
• I had to make some small tweaks in build script so that it runs in docker
• I added the template file for the config key

@nbarlowATI I'm sending this as a PR to your branch, but it would be good to merge your work into master if you're OK with that.
