5.0.3

Critical fix

• Add missing library in package

5.0.2 does not work, the library is not included.

Warning for npm users: If you set ignore-scripts=true in your npm configuration, remember that the prepare/prepack/prepublish steps of npm publish will be silently ignored 😠

Minor change

• Remove irrelevant "are you offline" log when elm/compiler#2095 occurs.
