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.
