- Fixed bug that caused the `Warning: Missing argument 2 for wpdb::prepare()` message to appear.
- Revised handling of logos and files again so that they are uploaded to `/wp-content/uploads/`.
- Added code to move logos and files from previous versions to the new directory.
- Corrected verbiage in some spots of the plugin to read as Listing instead of Business.
