[SNDVOL32]

- Fix more subtle bugs:
- Check with long line name if the current connection is activated when adding lines to dialog or when adding lines to the preferences dialog
- Use the temporary preferences context when writing the line settings
- Don't destroy the mixer when the preferences dialog is closed. the new mixer will be used for the application when the preferences are changed
- Pass the current selected line to the preferences dialog
