BaseNopModel.CustomProperites - not working with ModelBinder

[DmitriyKulagin]

nopCommerce version: 4.xx

Steps to reproduce the problem: Model Binding for Dictionary<string, object> is not correctly working.

when a form is posted back to a controller, those custom properties are not processed and do not exist on the model. Despite verifying that these values are posted in the POST DATA, the ModelBinder does not process those values.
