Fixed bug #5453 (WSA cleanup executes before MSHUTDOWN)

Fixed bug #5453 (WSA cleanup executes before MSHUTDOWN)

This moves the WSACleanup() call to after zend_shutdown() in main.c, I did some testing and I could not find any issues with this. I don't expect this to cause any issues on Netware either, although untested as I do not have such an env available (do we even support Netware anymore? Last release was in 2009 and it is now discontinued)

Besides the movie, then this commit also contains a fix to the check of WSAStartup() where we don't actually confirm we get the desired version of the winsock.dll (We use 2.0).
