This is pretty much similar to the value setting changes. This is a much
safer solution for getting values out of the scripting system which has
compile time validation for move-only types.
This commit changes the way the scripting API works by properly using
the newly available type information for moving the FSO resources into
the memory supplied by lua. This has full support for rvalue references
which will make it possible to use move-only types with the scripting
API.
This also makes the API much safer to use since it doesn't use pointers
to local values anymore which made it very hard to use the API in a
different context without causing issues.
This only covers writing the FSO values to Lua. Getting values back is
not covered yet.
This add a system for adding generic instances of the DynamicSEXP class
to the SEXP system. The only implementation at the moment is the LuaSEXP
which is used by the mn.addSEXP lua API to allow Lua to add new SEXPs.
Since this requires that FRED also runs lua scripts I added a mod table
option to enable scripting in FRED. Since the current scripts are not
built with FRED in mind it would likely break all these scripts if FRED
would be opened with normal scripting enabled.
This fixes#1320.
This adds a utility library for handling all the nasty lua referencing
stuff. It also provides functions for convienent usage of lua objects
such as tables and functions which allows to use them directly from C++
code without using the ugly Lua C-API.
