Don't reset the readline completer after each prompt...

Don't reset the readline completer after each prompt This makes it impossible to setup a custom completer. The comment says that "we must ensure that our completer is back in place," but I don't see why. All that does it make it impossible to use a different completer. One can trick IPython into not doing this by monkeypatching ip.has_readline to False, but then certain features like multiline editing are no longer enabled.
