Bug fixes:
- SHOWSTOPPER: SCSI scanners were never recognized as already configured, the user was always asked whether he wants to configure them. Problem was that device files are symlinks. - Made most ISDN and ADSL devices not being considered as a scanner by Scannerdrake, SANE does not support internet scanners.
