guile-tools is a scheme script that loads scheme modules
* meta/guile-tools: Changed to be a scheme script. Instead of looking for
executables in a "scripts dir", we just look for modules in (scripts),
and load the modules directly.
* module/Makefile.am:
* module/scripts/: Move the scripts into module/ so they can be compiled.
Rename scripts from `foo' to `foo.scm'.
* libguile/Makefile.am: Invoke the snarf->texi code via guile-tools.
* configure.in:
* .gitignore: Update for changes.
