1) install patches into separate directories to eliminate pkgsrc conflict
2) leave timidity configuration up to user, with instructions in MESSAGE
3) make timidity read configuration from PKG_SYSCONFDIR
4) bump PKGREVISION on eawpatches, guspatches, and timidity
foo-* to foo-[0-9]*. This is to cause the dependencies to match only the
packages whose base package name is "foo", and not those named "foo-bar".
A concrete example is p5-Net-* matching p5-Net-DNS as well as p5-Net. Also
change dependency examples in Packages.txt to reflect this.
