A new release so soon, but it's important as we had an issue
generating invalid MD5 sums in @SQ lines and slice headers in certain
situations.

Bug in the EOF block writing code. It was outputting
0xff 0xff 0xff 0xff 0xff instead of 0xff 0xff 0xff 0xff 0x0f for -1.

This caused the CRC to be invalid if you checksummed the raw data
instead of re-encoding it as Scramble does.

Also bug fixed the scramble -V option. Changing the version number
wasn't having any effect.
