b80d72e662 Better checks for Multiplayer API, prevent packet source spoofing. 
Fixes the following problems.

A malicious client was able to contact another peer faking its identity
(even looking like he was the server).

A malicious client was able to force other client disconnections by sending
bogus system packets to the server.

c1dc71baee Fix possible buffer overflow in NetworkedMultiplayerENet 
NetworkedMultiplayerENet::get_packet was reporting the wrong size for the packet buffer exposing a potential buffer overflow in case of malformed/malicious packets

8b9e5453a5 Use 2 different ENet channels for reliable/unreliable packets 
This avoids stalling other sequenced but unreliable packets
(i.e. UNRELIABLE_ORDERED) when sending RELIABLE packets.

-Ability to set compression to ENet packets (check API)
-Fixed small bug in StringDB that lead to duplicate empty strings

38338e90c0 ENet windows compilation fixes. 
For reference, when you include a Windows header (be it directly windows.h or something that includes it)
put it at the end of the includes. it seems I forgot.

3db36684b1 Added high level networked multiplayer to Godot. 
It's complete, but absolutely and completely untested, undocumented and NSFW.
Have fun :-)
