Start of new music using ABC and Csound.

Two basic, unfinished songs, written in ABC notation are added. The Makefile
will convert the .abc files to MIDI files, which are rendered using Csound. At
the moment, Csound is set up to use the Fluidsynth engine to render sound using
soundfonts, and the reverbsc opcode is used to add a reverb effect.

ABC notation is much easier to write music in than using "raw" Csound score
notation. Also, the abcm2ps utility can create very nice sheet music from ABC
files.
