Interface file reading
~~~~~~~~~~~~~~~~~~~~~~
Make interface files reading more robust.  
  * If the old interface file is unreadable, don't fail. [bug fix]

  * If the old interface file mentions interfaces 
    that are unreadable, don't fail. [bug fix]

  * When we can't find the interface file, 
    print the directories we are looking in.  [feature]
