DEV: Bump uglifyjs (PR #451)

GitHub

I am super happy with this but we are going to need to do a careful coordinated dance here. I guess the thing to confirm here is that

  1. Core fix is cross compatible (works with bot 3 and 2)
  2. Backport the uglify 3 support to stable / beta
  3. Bump the image

Cause we don’t want to break stable here.

Once you are ready with all the lego pieces feel free to merge.

Backport the uglify 3 support to stable / beta

I backported it to stable, do we need to cut a new beta to include it there?

We should probably cut a new beta anyway with the all the recent fixed @nlalonde
