Kickstart documentation has been moved

[Martin Kolman]

Hi,
the upstream kickstart documentation has been moved to Read the Docs:

http://pykickstart.readthedocs.io/en/latest/kickstart-docs.html

The documentation is now automatically generated from the pykickstart source code,
includes additional information such as when the given command or option was introduced,
should cover more commands and also contains a separate listing of commands for Fedora and
RHEL.

Thanks a lot Aleksandar Todorov, Chris Lumens and others who made this possible!

Best Wishes
Martin Kolman
