Move to managed lua

[AleksandarDev]

Use NLua

[AleksandarDev]

Pure C# Lua NLua is ~10x slower than C implementation.

Tested with for loop

local c = 0
for i = 1, 100000 do
    c = c + 1
end

Implementation	Score
C (C++) + C++/CX	3-7ms
NLua Pure C# Optimized	43-50ms

I decided to not implement Cross-Platform Lua. Rather, each implementation will be done separately for performance reasons.
