* Rebrand project to PiSCSI - rascsi ->piscsi - rasctl -> scsictl - rasdump -> scsidump - ras* -> piscsi* (rasutil -> piscsi_util, etc.) * Refined the formatting and wording of the app startup banner * Kept some references to rascsi and rasctl where backwards compatibility is concerned * Point to the new github repo URL Co-authored-by: nucleogenic <nr@nucleogenic.com> Co-authored-by: Uwe Seimet <Uwe.Seimet@seimet.de>
