Avoid accessing implicits that come from root imports that are hidden by some nested import.

This also changes the criterion when a root import is disabled.

A root import is now disabled if there is an inner import from the same package or module, and the inner import contains at least one disabling clause X => _. (The latter crierion is new; without it, we would consider something like

     import scala.{collections => c}

as a hiding import for Scala, which seems to go too far.)
