remove component remnants

[component.io](http://component.io) does not appear to be a thing anymore. This PR removes all the component-specific stuff from the codebase. More importantly, it makes `npm i && npm test` work out of the box without any additional environment configuration.

@ianstormtaylor, any objection?
