New identifier for save/open macro with user defined types

no version bump but B_USERTYPE defined

fix test from commit de26ef85 that should be nMaxRecords

tested full round trip on password protected document (ie. use binary storage)
master --(0)--> master --(1)--> libreoffice 4.4 --(2)--> master --(3)--> master

(0) in master, User type supported, big module supported
(1) in libreoffice 4.4, user type not supported, big module supported, no loss of code
(2) in master, user type not supported, big module not found, no loss of code
    it is OK as libreoffice 4.4 saves to LegacyVersion
(3) in master, User type supported, big module supported (all is restored)
    it is OK as module was saved with CURRENT_VERSION (see sbxmod.cxx)
