Always use uglify during build
Always use uglify during build

It makes very little difference between "npm run build"
and "npm run build --development" (both under a second),
since the gulp pipeline is smart enough to only uglify the new bits.

Creating different dist files with "--development"
is causing grief during pull requests, since most
devs will add the changed files without reviewing them.
It also means you can commit without stopping your "watch" npm task.
