Avoid loading readline in the kernel...

Avoid loading readline in the kernel This bit of code was loading readline even when there was no need for it. In a Qt console or notebook, try: 'readline' in sys.modules 'gnureadline' in sys.modules I plan to rework this code more extensively once we've switched to prompt_toolkit, but for now, this little fix should make the kernel start slightly faster.
