Add support for ViewComponent .with_collection

• No longer supporting rendering the component constant: render(MyComponent)

• Allowing components to render collections: render(MyComponent.with_collection)

Bumps rubocop dependency to 0.82.0

This locks the rubocop dependency explicitly, because rubocop has made breaking changes on more or less every minor (pre-1.0) release up until now. If you need to pin to a lower version, then the 0.14.0 release will still let you do that.
