Title: When gem uninstall would break dependencies, default to [yN] instead of [Yn].

When gem cleanup is run and removing a gem would result in dependencies not being met, the user is prompted with "Continue with Uninstall? [Yn]". It seems the preferred query would be [yN], so users can quickly hit return to decline to break dependencies but still cleanup old gems.
