    Correct logic of DisplayErrors
    
    Most directives (and other places with this specific directive) use 'or' logic to allow you to
    define directives in either `interchange.cfg` or `catalog.cfg` to enable a default-off behavior at
    either the Interchange server level or at the level of a specific catalog.
    
    As originally coded, the DisplayErrors directive would have only worked when *both*
    `interchange.cfg` and `catalog.cfg` had this enabled.
    
    Change this so it shows up when either the current catalog or the global config has this set.
    
    Since the old default was 'no', someone intended this information to be output, so this is the
    correct behavior, considering that I only fixed the output of this message in the previous commit.
