Add logWrap to global settings

`logWrap` is a configuration that allows for users to decide if when
viewing logs the lines should extend off screen allowing for scroll
behavior or if they should wrap at screen edge.

We also considered allowing users to toggle this setting at the Site
level but decided that since users would likely want this setting to
apply to all sites, we hoisted the configuration.
