Compile Lua as C++. When Lua is compiled as C, it uses setjmp/longjmp for error handling, resulting in failure to unwind intermediate stack frames. Trying to ensure no objects with non-trivial destructors are in scope when raising a Lua error is error-prone. In particular, converting an exception to a Lua error becomes convoluted, and raising a Lua error from a constructor is effectively impossible. Updated Lua to 5.4.4 - this includes a brand-new garbage collector implementation with better performance. The main thing removed is the deprecated bitlib. Updated sol2 to version 3.3.0 - this adds support for Lua 5.4 and fixes a number of issues, including not correctly handling errors when Lua is built as C++. Updated LuaFileSystem to version 1.8.0 - this adds support for symbolic links on Windows, as well as Lua 5.4 compatibility. Updated LuaSQLite3 to version 0.9.5 - this fixes issues in multi-threaded environments, as well as Lua 5.4 compatibility. Fixed double-free after attempting to construct a debugger expression from Lua with an invalid string, and exposed expression error to Lua in a better way. Added warning level print function to Lua. Fixed saving cheats with shift operators in expressions, although this code isn't actually used as there's no cheat editor.
