Revision 326272

change of plan -- let the wookie win. ;)

Avoid MANIFEST/"dist"/install issues, by limiting the rule filenames to just a
pre-defined set.

That way, we're back to MANIFEST containing the list of files in the "rules"
directory. That dir includes both code-tied (source) and rules project (built)
rules files.  The "rulescode" dir is gone, again.

The "rulesrc" dir is SVN-only, and not in tarballs -- the package produced by
make dist/make tardist etc. will contain the built rules files in "rules".
"make install" then installs those files.

This means that there may still be issues running "make install" from
an SVN checkout -- but it will always work from a tarball, since that
will contain the "built" files.

Non-"publish"ed sandbox rules are written to rules/70_sandbox.cf, and this file
is *not* installed.
