Allow to validate a custom schema with webpack.validate

SpaceK33z · SpaceK33z · commit 256d72beac56 · 2016-11-01T15:32:00.000+01:00
This makes it possible to provide a custom schema and provide it to webpack.validate.
webpack-dev-server and webpack-dev-middleware can then use this schema to validate their options in the same way as webpack does.
