Title: Raise HttpResponseBadRequest on upload if filename does not have an extension

Normally this would be caught by javascript, but if a person were to bypass that by, say, using curl..

```bash
curl -F "files[]"=@/some/path/FileWithoutExtension http://dumpon.us/
```

..then the detail view breaks. This commit prevents filenames without extensions from being uploaded.
