A little bugfix for Windows users not using Win client...

[PowerWyrm]

As I discovered when using SDL and GCU clients on Windows, the "quit" hook is not called when closing the console (resulting in a lot of memory not being freed) because the CTRL_CLOSE_EVENT is not handled.

The code below fixes that problem nicely. Declare a control handler function in the main-xxx file:

static BOOL CtrlHandler(DWORD fdwCtrlType)
{
    switch (fdwCtrlType)
    {
        case CTRL_CLOSE_EVENT:
            quit(NULL);
            return FALSE;
        default:
            return FALSE;
    }
}

And call it in the init_xxx function:

    /* Activate hooks */
    plog_aux = hook_plog;
    quit_aux = hook_quit;

    /* Register a control handler */
    if (!SetConsoleCtrlHandler((PHANDLER_ROUTINE)CtrlHandler, TRUE))
        quit("Could not set control handler");

Et voila! Closing the Windows Console now calls hook_quit(), which should call cleanup_angband() and free allocated memory properly.
