Fix CSS source maps, simplify dev mode

* Add "npm run" commands in package.json so that following README
  doesn't require npx or globally installed grunt-cli.

* Merge "default" task into "build" for clarity and simplicity.

* Remove unused Procfille and Heroku instructions.

* Remove unused Travis CI.

* Add GitHub CI.

* Fix source maps.

  With source maps fixed, remove the separate less:dev task.
