Minor changes to remove errors I was seeing in Puppet

Removed some non-ascii characters from within comments in some of the manifests.

These were causing errors with Puppet 3.0.2 each of these files would fail with "invalid byte sequence in US-ASCII at ..."  My environment is set to UTF-8, but I was still getting these errors.

Edit catch_errors.pp, keystone.pp,. ratelimit.pp, s3token.pp and swift3.pp to replace 
"François Charlier fcharlier@ploup.net" with "Francois Charlier fcharlier@ploup.net"
Edit authtoken.pp to replace "#  tempurl, …)" with "#  tempurl, ...)"
