Beta5 for Windows, Linux, OS X

Beta5 release! Moved a few things around and added a filesystem browser. The raw output and FS Browser are accessed by pressing +. The raw output checkbox and FS Browser button will appear on the main window giving you access to these functions. They are really probably only of use to other developers or curious folks who want to see how the V800 organizes files. Also added an icon for Windows and OS X.
