Remove dependencies on Subversion.

We no longer construct a fallback revision id by expanding $Revision$
in glyphs.py; instead, the bob build script is the only way to pass a
version number to the bob build, via --ver. Also, the version number
itself is moving to my new standard of YYYYMMDD.[opaque commit id],
making it more or less monotonic and also VCS-agnostic.

Make sure lilysetup creates its fonts subdirectories.

Turns out that the Lilypond data directory it's copying from may not
already have all of them, and if it doesn't, lilysetup will print no
end of annoying (but harmless) error messages.
