FileDialog: make the save/load distinction function properly

- shortcuts need to be different: use QStandardPaths::writableLocation
  if it's a "save" dialog
- that means shortcuts need to change dynamically, because the same
  dialog instance can be reused for both purposes
- DefaultFileDialog.qml changes its button labels accordingly
