Fix few QFileDialog static method issues in Symbian^3

- The selected file path now uses slashes instead of Symbian native
  backslashes as directory separator.

- If default file is specified in dir parameter of getSaveFileName in
  addition to directory, that will be used as default suggested
  filename.

- Clarified documentation a bit.
