Utilities updates for this week

• Volumouse: Added support for Windows key (in separated check-box) when using hot keys instead of wheel mouse.
  
  
• NK2View: Added support for backup/restore options. The backup is made in the same folder of the NK2 file, with .BAK extension.
  
  
• VideoCacheView: Added support for .SWF files (By default, this option is not enabled, because the cache may contains a lots of .SWF files, most of them are advertising)
