Sliceviewer does not save to image any more

[Alex Buts]

Tested on RHEL and Windows

If one looks at a workspace in the sliceviewer and tries to save it into an image (png), it behaves like it doing something but target image does not appear.

It used to work before.

What was happening is that you need to add the .png suffix, or the QPixmap method that is used to do the real saving won't write anything. I've fixed the code so that the prefix is added if the user doesn't add it.

To test:

Open the Slice Viewer for your favorite workspace(s), then do File->"Save to image file", giving any reasonable file name. Check that you get a file with that name and that the bitmap (png) looks like what you see in your Slice Viewer.

There are no tests for this and it doesn't look like the kind of thing that can be added as a unit test.
