Binary editor can't "Save as" deleted files

1. Open a file in binary editor.
2. Delete the file.
   Creator will notice this and will offer to "Save as" the file.
3. Select this option and try to save the file somewhere.
   Creator will write an empty file.
4. Scroll the binary editor.
   The binary editor will complain about the file being empty.

"Save as" should write an exact copy of the opened file. If this is not possible from the binary editor, the option should be disabled in this case.
