Added back in preference for gnureadline if it is present
Now that the crash bug in the gnureadline Python module which statically links against a compatible version of GNU Readline has been fixed for macOS, we added back in the top-level import boilerplate to prefer it if it is available.
Also updated some documentation in relation to getting readline installed for macOS.
