Implement saved connections restoration.
This is a bit hackish for now: it should only be attempted once, when the DLL is loaded on session login. Right now, it's attempt each time the DLL is loaded (ie, even when a program linking to it is started). This is to be fixed later on. So far, it brings the intended feature.

Now, you can create a connection with net use, save it, and reboot: it will be restored on the session opening.
