This optimizes the Dockerfile a bit by;
- putting the docs archives at the top to
optimize caching and to prevent having
to clone the github repository on each
build. Note that '--no-cache' is needed
to forcefully break the cache, but the
archives should not frequently change
- grouping RUN lines to reduce image size.
- using a loop for the archived versions to
reduce the amount of duplicated code.
- using the local files for the *current*
version of the docs instead of the git
clone from GitHub. this makes it also
use the right source instead of "master"
- adding a .dockerignore to prevent busting
the cache if not needed, and to prevent
uploading the '.git' repository, which
is not used for the "current" docs
