Need a refactoring this module.

Hi. :)

i reviewed this module code to fix several problem..;
When using some another modules, this module puts several warning. Especially, preprocess username function printed warning many times.

And, after uninstall anonymous posting module, anonymous posting field could not disable. Because, drupal says, that is still using..

And admin ui in admin configuration seems to be don't needed.
Now, if you checked type to use anonymous author, vertical tab show in content type edit page.
I think this is inconvienience. If enable/disable option exist in vertical tap per content type, it seems like drupal-way more than current way.

How about it?
