Lua API objs not listed in Lua.cpp

[MjnMixael]

Working on something else I came across this code comment

`/**

• IMPORTANT!
• For various compiler reasons, all scripting API classes and libraries need to be referenced here! The easiest way to
• do this is to declare the API elements in the header with the DECLARE_* macros and then include them here
  */`

The code then includes most of the scripting/api/objs header files and all of the scripting/api/libs header files.

I could not get the newer GlobalVariables API library working without including the header in this file. However, I know that all of the current objs are working without being listed here so it's not clear if that's a requirement. If so, then it'd be a trivial task for someone to just go down the list and add the missing ones. We should also, in that case, make sure we have a way to ensure that's done in the future as well when new objs are added.
