Moves the base image in r-ver and subsequent stack to debian:stretch (Debian 9.0, release 2017-06-17) for the 3.4.0, latest, and devel tags. Makefiles will no longer sync changes made int the Dockerfile latest back to the Dockerfiles of older versions. Those Dockerfiles are now stable and not expected to change further.
Most users should be unaffected by this change. Downstream Dockerfiles will benefit from newer versions of libraries and compilers, which will make certain packages easier to install on Docker (e.g. jags and GDAL libraries no longer need to be compiled from source since stretch binaries provide sufficiently recent CRAN versions).
