Win32: add the --win32log option to log stdout and stderr to files

Browse source 
Adding --win32log as the first command line option on Windows
will now log all stdout and stderr output to the files
subsurface_err.log and subsurface_out.log in the working directory.

This change required a new argument 'bool logfile' to be added to:
subsurface_console_init() which is defined in all platform files
(linux.c, macos.c, etc.)

Example usage:
subsurface.exe --win32log -v -v -v
