Adjust TextWidth subject line default back to 60

Upon further thought, there's no strong reason why a limit of 50
characters is necessary. 72 makes sense for email-based git workflows,
but 50 does not seem to have any strong reason.

Also, the default has been 60 for a long time, so let's keep it.

In the process, renamed some variables and configuration variables for
clarity.

Now that the Travis build is green again, we can add the badge back to
the README as it is now a useful signal.

This reverts commit 3ae530e27df6c2b3d6455f13b67c7d6d0ca6cb0d.
