Empty __init__ will allow us to use python namespaces with all of these
files. That may be something we want to take advantage of for allowign
them to be expanded by user dirs. Also might be needed for AnsiballZ or
other wrapper enhancements in the future.
* Make ziploader's ansible and ansible.module_utils libraries into
namespace packages.
* Move __version__ and __author__ from ansible/__init__ to
ansible/release.py. This is because namespace packages only load one
__init__.py. If that is not the __init__.py with the author and
version info then those won't be available.
* In ziplaoder, move the version ito ANSIBLE_CONSTANTS.
* Change PluginLoader to properly construct the path to the plugins even
when namespace packages are present.
