* Changed most occurrences of unserialize() to maybe_unserialize() to deal with changes to get_metadata() in WP 4.1.0.
* Removed 2nd argument from dfrps_upload_images() to deal with changes to deal with do_action_ref_array() introducing the $this parameter in 4.1.0.
* Fixed bug where large Product Sets made up of lots of individually added products were not importing or updating all products in the Product Set. This only affected individually added products in Product Sets with over 100 products.
