[IMP] add the automatic export of attribute.option, if the attribute is synchronizer with Magento then all option will be exported
[REF] start to refactor the image management. Finally I think that the default behaviour should as simple as possible even if some feature are missing (principally managing image in multi-store). Add the auto_bind_image that give the possibility to export image automatically without creating the binding. If you need to have different images by store for a same product then you should implement the feature in an external module, we may do it in the futur but for now I do not have customer that need it so I prefer to stay pramatic and make it simple
