Improve preferences display

When displaying preferences, color-code the base and admin
preferences similar to command help. Also show a placeholder when
there is no existing value set for a preference. Add a hyphen
separator between preference names and values. Update tests to
accommodate the new formatting, and while we're there add a test to
make sure non-admins can't set values for admin-only preferences.
