Implement document copy [PATCH]

[GoogleCodeExporter]

Attached is a working first pass at exposing CouchDB's document copy
feature. I have not added unit tests for but will do so if my approach is
the right one.

A couple of potential changes to the patch.

Right now the new Database.copy method requires a Document instance but it
could be made to take either a Document or just an ID like .get_attachment.

After the copy is completed the newly created Document is fetched and
returned. Perhaps the method should let the caller decide if they want to
fetch the new Document.

This was tested on CouchDB 0.9.0 so I cannot vouch it works for 0.8.x.

Thanks, added in r155. I've changed the implementation to only return the rev 
of the destination document.

Great. I've only glanced at the diff but is dest = src.items() what you want at 
line
372? Seems like that would copy the '_id' too.

Gah! Good catch, thanks :) Should be fixed in r159.
