Append page feature allows to upload images without filename extension

E.g. see document 91031. Obviously the upload did not accept the image files and the user appended the images to an existing document. Image files like that can not be handled by fimagestore http client and most jobs on such documents will fail.

Should this be feature of the fimagestore? We will have to deal with this problem for the images from NAF anyway...

On a fimagestore upload of a file with no extension we could try to determine the (img-)mimetype of the file from its content and add an extension if successful.

GUI prevents this already
