Various fixes for MS Office problems (two versions on edit/save, version generated when file opened and not changed (ACT 3691).

Added file access/change/modification timestamp tracking for open files via the file state cache.
Added set file information support for setting creation and modification timestamps, used by MS Office to transfer original timestamp to new document.
