Variable types support

[faseceroo]

Hi, I'm just thinking out loud here. Unlua is the most complete scripting solution for Unreal by far. It supports event dispatchers, Unreal interfaces, Class inheritance and it can read BP variables without even need to pass them as parameters.

However, Lua is a dynamically typed language and variables do not have types. This makes very hard to mantain big projects IMO.

It would be great the addition of a fork from unlua supporting variable types, like Teal or Nelua, which are typed dialect of Lua. I don't have the knowlegde of doing something like this but I think it would be a fantastic upgrade to this amazing project.

Just my two cents, thanks for creating Unlua :)
