integration of enet on the server side, streams and data vectors removed

- read moved to packet, write outstanding, string improvements, command
editor is a global console reader with less string copies, replaced
headers in types with own types and static asserts

+     *  that an unreliable packet should not be dropped and thus sent by ENet to the peer.
+     *  The lowest mean round trip time from the sending of a reliable packet to the
+     *  receipt of its acknowledgement is measured over an amount of time specified by
+     *  the interval parameter in milliseconds.  If a measured round trip time happens to
+     *  be significantly less than the mean round trip time measured over the interval,
+     *  then the throttle probability is increased to allow more traffic by an amount
+     *  specified in the acceleration parameter, which is a ratio to the ENET_PEER_PACKET_THROTTLE_SCALE
+     *  constant.  If a measured round trip time happens to be significantly greater than
+     *  the mean round trip time measured over the interval, then the throttle probability
+     *  is decreased to limit traffic by an amount specified in the deceleration parameter, which
+     *  is a ratio to the ENET_PEER_PACKET_THROTTLE_SCALE constant.  When the throttle has
+     *  a value of ENET_PEER_PACKET_THROTTLE_SCALE, no unreliable packets are dropped by
+     *  ENet, and so 100% of all unreliable packets will be sent.  When the throttle has a
+     *  value of 0, all unreliable packets are dropped by ENet, and so 0% of all unreliable
+     *  packets will be sent.  Intermediate values for the throttle represent intermediate
+     *  probabilities between 0% and 100% of unreliable packets being sent.  The bandwidth
+     *  limits of the local and foreign hosts are taken into account to determine a
+     *  sensible limit for the throttle probability above which it should not raise even in
