Juan Cruz Viotti d521fbbd2c chore(CLI): minify Etcher CLI code (#1401)
UglifyJS v3 was recently released, which includes support for
compressing ES6 code.

This commit introduces the following changes:

- Add a boolean `-m` option to `concatenate-javascript.sh`, which when
  set, will minify the final concatenated JavaScript file

- Install `uglify-es` in the CI servers
