Title: Don't try to copy readline on Windows

Fixes a variant of #4 for Windows. Normally there is no readline module on Windows, though there may be one in site-packages if [pyreadline](https://pypi.python.org/pypi/pyreadline) is installed, leading to a crash like the one described in #4 when running `virtualenv.py`.
