Fix the import path for get_slugify

[pydanny]

At the moment, I can't do:

from slugify import get_slugify

I get an import error because of how slugify.__init__.py is defined. Instead I have to do the following:

from slugify.main import get_slugify

I would like to either submit a patch to slugify.__init__.py or correct the documentation. @dimka665, what approach would you prefer?

Fixed. Thanks.
