Workaround to move comments with phpMyAdmin

Issue Summary

At least while Comment Mover is in Do not use on production sites status, I think a workaround to move comments with phpMyAdmin by editing nid and other fields in the comments table would be useful to users, and a welcome addition to the Comment Mover documentation. See the edit the database comment for details on how to do this.

This workaround moves comments directly, without leaving redirect links in the original nodes. However, it has the advantage of keeping cid and therefore chronological order.
