* Modernize font creation * Automate the build process, instead of writing a complicated manual * Update sources used by the docker image away from google code * Exclude MathJax-dev checkout from docker image, to allow image reuse * Try to keep the individual image layers small by combining RUN commands and removing temporary files used only during each individual step * Allow creating fonts from local directory Also use hash of Dockerfile to compute image tag, in order to ensure creation of a new image if the Dockerfile changes. * make glob syntax work on MacOS
