Docker support with repeatable build (#255)
Dependency to `git` has been removed, we now use `notag` when building without a git directory. In order to reliably fetch all dependencies, we do a first blank build (with no source files), then we copy the sources and do a real commit. This is a simpler and more robust approach. Also, fixed the .dockerignore to filter out IDE files.
