Feature Request: Offline usage

[andrewcio]

I realize that this only works when connected to the internet. A way to load the ATDL checker locally as part of the package would be preferred but this would bring updating issues when the tool itself has updates.

I also noticed this in the README.md

uses after the dead line web service: http://afterthedeadline.com/

Does this send the whole document to a remote service to be spell checked?
