esprit update, ticket priority system

New esprit update scheduled for 3 AM EDT:

• Added: prefer slave billing server, fallback to master billing server if unable to contact primary billing server
• Added: trouble ticket priority system
• Fixed: leading forward slash in forbidden files in File Manager
• Fixed: CSC changes: nag on missing CSC only if card number changed or no csc + card number unchanged and first access; further, deny credit card updates without CSC provided
• Fixed: Impromptu display bugs in IE
• Fixed: Misc Majordomo fix-ups: missing majordomo-owner alias, removed -w check on majordomo directories as -w doesn’t handle ACLs
