Merged DEV/TEMPORARY to HEAD

23222: ALF-3707: Alfresco Sharepoint protocol and Office 2010 issue
      Problem related to incorrect response of VTI WebDAV Lock method for Windows 7 clients was fixed. 
      Requested refactoring was done:
      - Code duplication was removed from VTI Lock, Unlock, PropPatch methods. 
      - Changes related to inheritance were added to original WebDAV methods.
      - VTI Propfind implementation was detached from original WebDAV PropFind
      - Logging was added for empty catch blocks 
      - Unused import was removed
      - Unnecessary empty catch blocks were removed
