volunteer for patchy new-patches

[Graham Percival]

I think it's high time for somebody else to run the new-patches
test.  For this task, David is ridiculously overqualified, but his
laptop is pretty underqualified.  That combination makes him
almost the worst person to run this task.

I'm hoping that this won't end up with James doing it; IMO even
James is overqualified to be running patchy new-patches.  But
maybe that would be ok for a week or two, in order to catch some
more "gotchas" in the script and docs, then pass it on to another
person.  Maybe one of the bug squad members?

NB: this is *not* a review, nor does it require any knowledge of
lilypond programming at all.  You run a script, if it finishes
then you look at some pictures and then say "nope, no change to
the pictures".  Once you have the script set up -- which is easier
than the patchy staging-merge, BTW -- it's easier than being a bug
squad member!

On a more general note, I've love it if we could start foisting
off some more development/maintenace tasks onto the current bug
squad members, and start recruiting some new bug squad members to
replace the existing ones.
