Small bug in unit_advancements_aspect.hpp

[forceOfHabit]

I'm new to these fora, and I didn't see anywhere to report a bug, so I stuck it here. If this isn't the right place, feel free to point me in the right direction.

Anyway, I'm pretty sure line 21 of unit_advancements_aspect.hpp should be changed from

#include "lua/lualib.h"

to

#include "../../lua/lualib.h"

I found this when trying to compile the stand alone version of ai/attack_prediction.cpp.

you need to tell your compiler to consider /src as include directory.
