Change download location for Windows from scapy.net to hg repo

The ZIP file available at http://scapy.net/ has an additional header to
make it startable on Linux. This confuses the Windows internal unzipper
and causes warnings about corrupted archives. The files can be
extracted with 7-Zip or InfoUnzip, but this might be inconvenient
for a lot of users. So we now point to the Hg repo which carries
an unmodified ZIP.

 You need the following software packages in order to install Scapy on Windows:
 
   * `Python <http://www.python.org>`_: `python-2.5.4.msi <http://www.python.org/ftp/python/2.5.4/python-2.5.4.msi>`_. `python-2.6.3.msi <http://www.python.org/ftp/python/2.6.3/python-2.6.3.msi>`_. After installation, add the Python installation directory and its \Scripts subdirectory to your PATH. Depending on your Python version, the defaults would be ``C:\Python25`` and ``C:\Python25\Scripts`` or ``C:\Python26`` and ``C:\Python26\Scripts`` respectively.
-  * `Scapy <http://www.secdev.org/projects/scapy/>`_: `latest version from the Mercurial repository <http://scapy.net>`_. Unzip the archive, open a command prompt in that directory and run "python setup.py install".

   * `WinPcap <http://www.winpcap.org/>`_: `WinPcap_4_1_1.exe <http://www.winpcap.org/install/bin/WinPcap_4_1_1.exe>`_. You might want to choose "[x] Automatically start the WinPcap driver at boot time", so that non-privileged users can sniff, especially under Vista and Windows 7. If you want to use the ethernet vendor database to resolve MAC addresses or use the ``wireshark()`` command, download `Wireshark <http://www.wireshark.org/>`_ which already includes WinPcap.

This is a *special version for Scapy*, as the original leads to some timing problems. Now works on Vista and Windows 7, too.
