Adjusted input splitter to allow newlines in string literals.

Implemented Windows build for OdeCxxBox's user-supplied code.
Implemented command line arguments. Working on box description (-d option).
Implemented escaping in string literals printed with the -d option.
Added -i option (force interactive). Added list of box types printed with -d.
Added more MSVS versions to OdeCxxBox build script for Windows.
