Added 64-bit Windows build through SCons.

The SCons build now supports building for 64-bit Windows. This still requires that the SCons build is passed an env parameter containing the PATH and LIB for the 64-bit build as SCons autodetects the 32-bit environment.

Lowered the warning level for the 64-bit build temporarily.

Added a verbose option to SCons to display the startup banner for the Microsoft Visual C++ tools.
