Merge pull request #13 from phillipkent/fix_bug_windows_readline

fix bug in using readline in WindowsI found a bug with use of 'readline' for Python 2.7 on Windows 7. Cloudmonkey fails to run with this error:

File c:\python27\lib\site-packages\cloudmonkey\cloudmonkey.py  line 70 module>
            If libedit in readline.__doc__
TypeError:  argument of type NoneType is not iterable

It requires modification of cloudmonkey.py at line 70.

The error and fix are the same as reported here:
http://bugs.python.org/issue18852
https://hg.python.org/cpython/rev/3070fdd58645

Note: I haven't tested this for Cloudmonkey in other Windows versions, or other Python versions.
