Error uploading hidden UNIX files

[bratekarate]

When uploading a hidden file from a UNIX system -- that is, a file that starts with a dot (.) -- an exception is thrown from within AttachmentableService.

The Exception is caused by an invalid instance of the type Attachmentable: The file name is missing. Apache Commons FilenameUtils is used by AttachmentableService to retrieve the basename of the file. Unfortunately, this does not work for hidden files; getBaseName just returns an empty String, because it thinks the dot introduces the file extension.

If there is a workaround for this issue, I will be happy to use it.
