Subject: [PATCH] Fix in ppi config and relative path fixes.

PPI config had an extra character appended to a numerical value.

There are several places in a boltzdesign.py script where paths are
relative to cwd or a workdir, but should be relative to script_dir
instead. With these changes, script works when invoked outside of
BoltzDesign1 dir.
