Implemented most of file viewer functionality. Can now view all types
in some format; Applesoft BASIC is color coded; images can be viewed; hex dump is shown; simple text transformation is done for nearly all formats; raw dump isn't implemented correctly yet. Printing is done for anything that uses the StyleText widget.
