Winsock error handling fixes

This branch (hopefully) fixes any SOCK_Send errors producing the useless #0: No error nonsense that people have been reporting for a while now for Windows versions of SRB2. While it doesn't fix the cause of the errors, it should correctly report the error codes for them now. And if I did things right, it should actually print an actual message for the error as well now.
