* fix: script manager and lua scripts: change the api so that the m_scripts array is only modified in a specific safe location: before it gets ticked.
* fix script manager: don't expose the script vector directly, for multithreading safety
* fix lua manager usage: don't iterate the module array without locking, nor un/load module from a script thread
* lua script: only do actual loading of lua modules in script mgr
* lua native bindin: fix pointer parameters, out C style parameters are returned as multiple return values lua-style
