New issue 1686 by address@hidden: Compile scheme files to scm/out  
when using Guile V2.n.  Also load and run .go files if available
http://code.google.com/p/lilypond/issues/detail?id=1686

When running with Guile V2.*:
1. Add ability to run Lilypond to compile all the scheme files in /scm to  
produce /scm/out/*.go files.  Add option -dcompile-scm-files so Lilypond  
can be run up to do this during build.

2. Add facilities to search and load compiled /scm/out/*.go first and only  
fall back to interpreting scm/*.scm file if this does not exist.
