This change allows the blacklight_advanced_search plugin to properly install when the application already has an existing search history and saved searches controller, adding the range limit behavior to the controllers rather than overwriting them. The range limit plugin also modifies these controllers so this change makes it easier to install a blacklight application that uses both plugins.
Parallel with projectblacklight/blacklight_range_limit#63.
Rebased.
