Both "Create Executable" and the module browser use `get-module-code'
from (lib "moddep.ss" "syntax"). I've changed this function in CVS so
that it ignores extension files (including _loader files) when source
or ".zo" is available.

I also added an optional argument to `get-module-code'. The new
argument is a procedure to be called when only an extension is
available. Probably the module browser should provide this argument and
treat extension-based modules as having no imports.
