Views integration: Please provide an author is a buddy of UID argument handler (patch included)

Hi,

The current views implementation does not provide any argument handlers except when the usernode module is installed, and even then the argument handler is only for usernodes. It would be more useful if the argument handler worked for any node that the UID is an author of, and then a separate filter could be used to narrow the results down to any content type - be it usernode or any other type.

I need this functionality, so I have written the code for it. I copied the existing implementation for usernodes - I just had to duplicate it and replace each occurrence of 'usernode' to 'node'. Please include it if you agree.

Thanks,

Zoltan
