  Modified files:              
    /loncom/interface	loncommon.pm 
  Log:
  - Updated domain configuration interface allows modification of a few components at a time - potentially leaving others still using data/files from the legacy definitions in lonDomColors and lonDomLogos (for older domains).
  - Retrieve legacy data when displaying pages for domains that have partially transitioned to storage in configuration.db
