godot/scene/main/scene_main_loop.cpp
Juan Linietsky cbbcf72703 -High Level protocol optimization (should be smaller) 
-Ability to set compression to ENet packets (check API)
-Fixed small bug in StringDB that lead to duplicate empty strings
-Added a new class, StreamPeerBuffer, useful to create your own tightly packed data
