  ZP-824 Remove local $sc as it is not needed.
  ZP-825 Rename ReplaceNullCharFilter classname, register filter in WBXMLEncoder before it is being used.
  ZP-824 Invalidate all pingable flags on folders when doing a FolderSync (with changes) or FolderChange (Create, Update, Delete) operation.
  ZP-707 Remove debug.
  ZP-707 use MAPIStreamWrapper where possible.
  ZP-823 Remove empty line.
  ZP-823 Do not sync suggested contacts folder.
  ZP-708 Wrap the plaintext body, html body or mime message into a StringStreamWrapper. While the wrapper correctly truncates (UTF-8 compatible), we can also truncate before loading the data in.
  ZP-817 Set task as private if sensitivity is private or greater.
  ZP-808 Set appointment as private if sensitivity is private or greater.
  ZP-781 Use comma as decimal and dot as thousand separators, add 's' as unit for time usage.
  ZP-781 Nicer format for memory usage.
  ZP-817 Unsetting private task in Outlook is not saved on the server.
  ZP-793 Cache requested folderid so only the SyncCollections get changed that really had a change in flags.
  ZP-817 Sensitivity (private) of tasks is not saved on the server.
  ZP-766 Accept outlook response schema on autodiscover, send XML response only for mobile response schema or empty otherwise.
  ZP-641 Make sure CleanStates does not touch permanent backend storage files, unless we really want to delete them.
  ZP-641 Revert "For Backend Storage type files, add a user element to the file name so that multiple accounts on the same device do not overwrite each others data in a single file named only for the device."
  ZP-682 Compare the configured LOGBACKEND lowercase.
  ZP-682 "filelog" and "syslog" classes can not be found by autoloader (because they are in camel case and not lowercase). Rewriting the backend loaded by ZLog to the class name, as this is more end-user friendly. Throwing a FatalNotImplementedException causes a recursion that eats up all available memory before it fails, as that exception tries to log which then throws the exception again.
