Improvements to dist.sh, to fully utilize Python distutils, avoiding the need
to unpack, tweak, and repack the tarball generated by them.
* MANIFEST.in: Remove cvs2svn, already handled by setup.py.
Add MANIFEST.in, cvs2svn.1, svntest/*, test-data/* and www/*.
Ignore the svn:ignored files in www here as well.
* dist.sh: Add set -e.
Modify the version-number replacement logic, and remove the
unpack-tweak-repack logic.
