Fixed streetlamp LODs, which weren't reallyworking. Street lamps would just disappear entirely at low LOD. Also disabling their wispy particles now at far distance. Tried disabling the light too, but it's too obvious when the lighting changes at any distance.
[D11] merge 28975, 31306, 31323, 31325 from main branch to bring over entity streaming optimizations and dos fix. Nb parts of these changes are raknet specific but I don't think this matters too much, we can replicate those parts if necessary in litenetlib. Increased network protocol to force server upgrades.
