1. Use "cp", not "install" tool, to setup rEFInd in the setup script
2. Add rEFInd to iso at (ISO)/packages/refind-bin.zip
3. Use "cp -f" and "cp -rf" everywhere
4. In update-iso.sh, make sure updated setup script is copied to
(ISO)/arch/setup apart from updating the same in the initramfs files
5. Fix FSSPECS issue (in for loop) in autoprepare() in setup script
6. Added /usr/sbin/partprobe , /usr/bin/{bsdtar,bsdcpio} in arch_base
- useful for rescue stuff and needed for setting up rEFInd
7. Split up EFISTUB and rEFInd functions
