And some subtle grammar.

Closes #64

It is autogenerated.

Closes #60.

Suspect it is causing sphinx to crash on readthedocs. See
https://github.com/sphinx-doc/sphinx/issues/1871

Not required as we are not documenting the source code.

See #60

this should also be backwards compatible with python 2

Fix the following error. Looks like we have to have a function to call
for the entrypoint.

These files were included, however just to make sure.

Closes: #61

Using --disable-ipv6 will now force sshuttle not to capture
ipv6 traffic, even if the client supports ipv6.

See #57 for details.

This reverts commit b4b283b2.

Should work even with different python versions on client and server.

This fixes the following error:

    "import_name": entry.suffix.split(".")[0],
    AttributeError: 'NoneType' object has no attribute 'split'

See
https://pythonhosted.org/setuptools/setuptools.html#automatic-script-creation

This should solve the TypeError reported in #53 and some others I found
while testing the fix.

Closes: #53

The PF firewall that is included in the FreeBSD base system does not
have exactly the same data structures as the OSX version. This commit
fixes the offsets and some field types that are also different. Tested
with FreeBSD 10.2 and OSX 10.11.2.
