add accuraterip element

Morituri[1] calculates AccurateRip checksums[2][3] of the data it ripped to
check if the ripping is fully accurate. It currently does this in python, but
this is really slow. The attached patch adds an element doing this computation,
and it's much faster (in my testing, I could compute the checksums for the
whole CD while the python code was still processing the first track). It's
heavily based on the chromaprint element.
