GameSetup: ensure all ScriptingInit are called; moved simulation
ScriptingInits and init/shutdown to SimulationScriptInit.cpp (reduces
#includes)
This was SVN commit r6028.
replace ONCE with direct calls to ScriptingInit in simulation/network
code as well.
note: GameSetup is now responsible for calling ServerSession's init
instead of Server doing it
added simulation/scripting with a module that takes care of all
scripting init (reduces CCD)
This was SVN commit r5883.
