Line ending cleanup to help Windows

This request has a couple of commits to address log messages that use '\n' for line endings, instead of the system line separator.

I found most of these by way of `git grep '\\n'`, though that also comes up with some exception messages and some HTML output that I left alone. I tried to keep the change focused on log files, which are awkward to read on managed servers that might not have tools that can handle Unix-style line endings installed.
