Dan Hersam 2d8e15a565 Version uses binary name instead of hugo
On Windows the binary name is hugo.exe and running hugo version results in
this error:
    GetFileAttributesEx D:\Dev\Go\gopath\bin\hugo: The system cannot find the file specified.

This fixes that error and allows the binary name to be something other
than hugo on any OS.
