SaveAs Dialog fixes: QG_FileDialog
This patch first removes an unnecessary break in the function QG_FileDialog::getExtension
The second part reworks most of the function QG_FileDialog::getSaveFile in order to give a
  default name of Untitled (where an incrementing # is added if Untitled already exists).
  This consequently stops the last folder from being selected as the new saveas file.
dxfrw: added write spline support
