Title: Remove the upload field type hack

In the old days - the file upload field required we add the attribut `encoding="multipart/form-data"` to the post edit form. It was a bit hacky really as it had to check whether an upload field was present and then use JS to insert the attribute. But now we're using the proper file uploader - so this isn't actually necessary.
