Every score on the disk, not a named one

The makefile compiled splash.score by name, so intro.score sat beside it
turning into nothing - which is exactly the failure the mirror three
lines above exists to prevent, and its comment says so: a list in a
makefile goes stale the moment somebody adds a file, and what they forgot
is invisible until they go looking for it on the machine.

Found by the user going looking for it on the machine.

Every .score in Programs/Tunes is compiled and put on the disk now, and
every patch in Programs/Sounds is converted first so a score can name any
of them. The source is mirrored to /Source/Tunes with everything else
that was written; the tune goes to the root, where a program looking for
one expects it - which is worth writing down, because the two being in
different places is the thing that sent somebody hunting.

two.score moved to Tests. It is a fixture, it names patches that only
exist in the test build, and it was in the music tree only because that
is where scores were when it was written - which the game disk build
found immediately by failing to compile it.
