[~BUGFIX] Inserting of image into catalog_product_entity_media_gallery_v...

When inserting images using this branch, the images weren't imported. I added a echo $e->getMessage() on line 866 in AvS_FastSimpleImport_Model_Import_Entity_Product and got this message;

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'disabled' cannot be null

So I changed line 859 to include a default value of '0' for disabled when it is not found in $insertValue.
