* new:dev: create docker image to build the class site
* move scripts into docker folder
* chg:dev: switch to ubuntu since alpine texlive is broken
* chg:dev: add make rules to build and publish docker image
* chg:dev: switch travis to use docker image
* chg:dev: add time to docker make rules
* chg:dev: try building with minimal texlive
* new:dev: add make rule `dockerrun` to run the image
