Rebrand project to PiSCSI (#1016)
* 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
