psychon 94f64333ca Fix a bug if a user uses /version ...

/version generates a 005 server reply. We used to cache this reply in the raw
buffer and the next user who logs in then received the same 005 reply multiple
times.

We fix this by adding CBuffer::UpdateExactLine() which does nothing if the exact
same line is already in the buffer. The only place where we (currently?) use
this is the raw 005 reply.

This should fix sf bug #2817124.
