Fixed a bug in showing the reading-frame translations. It's a 1 byte
buffer overrun that has existed since ~2002.

Improvements to Shuffle Pads's validate_clip() function. Using a
similar method to rewrite_soft_clips (possibly the validation should
be merged into that code), it now counts differences to the
consensus.  This is often more reliable than counting SNP consensus
bases when faced with highly varying read depth.
