win32: optimize the console and logging logic

Currently one has to explicitly use --win32console and/or
--win32log to enable a dedicated console (a console window
that opens next to the Subsurface window) or to enable file
logging on Win32.

This patch makes the following changes:
- removes the --win32* command line arguments
- removes the dedicated console window support
- if the app starts from a shortcut and not from a console, always
redirect stderr and stdout to _err & _out log files
- if the app starts from a console redirect stderr and stdout to that
console
