Title: Added additional status codes

I needed this for my purposes, but it can't hurt to have them:

I used 406 to determine if the requests from an automated system were acceptable, and 409 to let the same system know an entry already existed (i.e. duplicate). The system would retry otherwise, which led to faulty behavior.
