Notice when global settings have not been saved

When the global settings have not been saved prior to the first decoration being created, a notice occurs in table_trash.module, line 113.

The patch below solves this by setting 'module' as the default library source to use.

diff --git a/table_trash.install b/table_trash.install
index a7b8855..9c824f8 100644

   }
 }

PS: would have committed this myself, but having issues with Git at the moment.
