* Sockets will now always be nonblocking on win32 version of InspIRCd. There were some cases (mainly in TreeSockets) where a socket would not get restored to nonblocking mode after a connect() call, resulting in the server getting stuck on a blocking send() call causing freezeups.

* configure will now compile under VC7 again.
