    Added EDS_ADDRESS_BOOK_MODULES and EDS_CALENDAR_MODULES
    
    Allows specification of alternative paths to search for modules
    for addressbook and calendar. Note that these *replace* the default
    system path, not augment it. This is intended to ensure that we
    dont load installed modules from the system when running test cases.
