Moved files to another repo.

Moved these files to the "autoupdate" repository, which is now the
preferred location for update.properties and binary files for Protege
plug-ins that are accessible through the auto-update mechanism.  New
location for files is:
https://github.com/protegeproject/autoupdate/tree/6ad2ad3bedde7a4a7b3efa82c39965b8885b1155/dlquery.
