Setting for Display for Anonymous users does not hide Utility Bar

Anonymous users will see the Utility Bar even if the Display utility bar for anonymous users setting is switched on. That's because the _utility_bar_display_utility_bar() function does return TRUE for any of the variable utility_bar_display == 1 cases. It must return FALSE instead if variable utility_bar_display_anon == 0 (or is not set). Just removing the second return TRUE solves the problem.
