Dave Ward 658e968320 ALF-11957: Merged PATCHES/V3.4.6 to HEAD
32617: ALF-11879: IMAP performance
      - Fix node batch loading - batch load ContentData to avoid N+1 problem with content properties
      - During cache preloading, use distinct transactions for each folder search, thus avoiding blowing the transactional caches
   32619: ALF-11879: Fixed typo
   32652: ALF-11879: Deactivate auto-versioning and auditing (and run as system) whilst setting magic IMAP aspect properties
