• database_api.php
  (db_query): add a second parameter (with a default value) that allows you to indicate you'd like a return value of false instead of an error if there is a problem. This should be used very infrequently but I'm adding it so that the admin upgrade script can check whether a table exists (the query fails if it doesn't)
