The help (?) links throughout the client pointed to the old
www.audiobookshelf.org/guides/* pages, which no longer exist and
resolve to a 404. Update all of them to the current
audiobookshelf.org/docs/documentation/* locations.
This commit moves the Users settings page to use the new Settings
Content component. Similar to the Libraries page, this one is already a
component. I mimiced the behavior of the existing libraries component to
get the same functionality needed here
