Replaced ENet with submodule

This also updates ENet from 1.3.2 to 1.3.18.

The previously supported WITH_BUNDLEDHEADERS option that affected which
ENet was being used has now been reversed and renamed to
USE_SYSTEM_ENET, which defaults to OFF for now.

-/** Configures throttle parameter for a peer.
-
-    Unreliable packets are dropped by ENet in response to the varying conditions
-    of the Internet connection to the peer.  The throttle represents a probability
-    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, on 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
-    the best of conditions.
-
-    @param peer peer to configure 
-    @param interval interval, in milliseconds, over which to measure lowest mean RTT; the default value is ENET_PEER_PACKET_THROTTLE_INTERVAL.
-    @param acceleration rate at which to increase the throttle probability as mean RTT declines
-    @param deceleration rate at which to decrease the throttle probability as mean RTT increases
