[Avodah] new editions

[Zev Sero]

The Rambam is known to have constantly tinkered with the Yad, and since
he published it through a "print-on-demand" house (i.e. his scriptorium)
he was able to introduce changes as they occurred to him, without a formal
edition or release number.  He did change a few pesakim over the years,
though I can't cite any examples.
