Title: Prevent error if content_type or tag_category are 'None'

content_type and tag_category are Nullable fields in the model, and executing Tag.add(tagname) will create a tag where those fields are null. The add_tags() function, however, will crash if the value supplied for those fields are None. This update will correct that issue so that add_tags() will handle 'None' parameters.
