correctly receive data immediately following a SOCKS5 message (closes #64)

The SOCKS5 client and server would discard any currently buffered received data
when processing a SOCKS5 command as they used readAll(). Now they only consume
the SOCKS5 command's bytes, preserving any buffered data.

Why this situation should occur is a different matter, I would be surprised to
see it happen during file transfer, due to the sequence in which the handshake
is performed.
