Removing "Null Framewerk" message

[Canardia]

You can comment out line 55 of environment_athmosphere.lua, to get rid of the "Null Framewerk" message when using a sbx scene from C++:

	-- Notify("Null framewerk.",1)

This lua script expects that framewerk is loaded, but it's impossible for it to have framewerk, since it's only available in C++ when writing games with C++. However, the script could be changed to use global lua variables instead (instead of accessing the fw object directly), but then you would still need a C++ function to read those global lua variables and set the framewerk values accordingly. But since gamelib 0.0.15.0 loads the settings from the Athmosphere entity anyway in C++, it's no big deal.
