* New extra-files field, and `render' installs them
(the render of multi-html copies these files to each directory)
* Add an ++extra argument to the scribble command line
* Fix output of the indirect renderer
svn: r13966
* scribble.ss is gone (ot was doing the running, which run.ss defined)
* converted run.ss to scheme/base
* added private/indirect-renderer which can be used to build renderers
that are based on conversion from the result of an existing
renderer, obviously useful with the latex renderer
* added pdf-render using this and private/run-pdflatex
* added a --pdf option to run.ss
