Fix for message-edit-3 blowing up. Tested on both PG and Oracle. Thanks
go out to Louis. - Arjun
"In digging into the code I found that there is a call to
bboard_message_clear_categories which in turn calls db_dml to call a
stored proc. This doesn't seem to work, but changing the db_dml call
to db_exec_plsql seems to have resolved the issue." -- Louis Zirkel
