* Set "Ctrl+Shift+S" as shortcut for "Save as..." in CvPcb and PCBnew.

  This seems to me like the defacto standard for this menu command.
* Added a default filename for save as. Currently it's set to
  "Unnamed file" using _() so its translatable.
* Changed the save dialog in PCBnew to use the path of the "original"
  file as a base for the new file.
