Copy humans.txt and robots.txt to dist/ (PatrickJS#1076)

Fixes issue PatrickJS#1070

The standard for humans.txt and robots.txt says that they should be available from the root of the application. This change will make sure that they get copied from the assets folder to the dist/ root instead of to dist/assets.
