Update BicBucStriim SPK

This corrects the issues there currently are with the BicBucStriim package. Tested on DSM4 and DSM5.
Changes:
- Update to BBS 1.2.2
- Set open_basedir to None, removes need for wizard (we can't set the ebooks dir via a wizard, as BBS saves the location in a database)
- Add DSM5 compatibility
- Add beta flag
