2 Mat and Frame enhancement requests

[Winfried]

1) The name of the generated image is "Untitled xx", but there is no link/relation to the original images.
This has the effect, that there is no "default" filename when saving the file. That is quite inconvient.
I tried the"Save as Widget" dialog to automatically save to a file %filename%-framed, but this does not work becuase there is no filename. %filename% is empty.

2) The generated image does not contain exif-data. It would be nice to have the exif/meta-data from the orignal image copied to the generated "framed" images.

I need these functions to automatically connect the original images to the framed-images within my DAM-tool (IMatch 5 Beta).
