add profile timer, near updateTilePhysicsObjects, increase player spawn

cut out (the whole thing is a hack that'll break in any real world
scenario of course).

that functions is very expensive though..taking 6-12ms on my desktop.
Now, this is on the server thread, but client has no interpolation, so
it feels everything. Hopefully this is the problem.
clear all the CXX_FLAGS except the C++11 one...

this whole thing needs cleaned up but right now I'm busy trying to optimize
a very latent area..
set duplicate peers limit on server to prevent (DoS) SYN attacks

this may need increased if several people want to play the game behind
the same router...(e.g. family)

but i guess i'll worry about that when i get > 0 other people "playing"
the "game" ;p
