a49a5bb781 AIN build and saving now fully works
AI is pretty much completed.
All that has to be done currently is making a simplified mesh of a map to cast a NavMesh on.

b99f310198 Parsing Titanfall 2 AIN's now fully works
The AIN structure, including the in-memory structures seem identical to Titanfall 2. I mapped quite a few 'CAI_Network' related functions out and everything seems to line up. But I haven't figured the script nodes out (yet), but looking at this, it seems like they got completely stripped? TODO..

I also found where it creates nodes/links from input NavMesh, the poly structure also seems identical to Titanfall 2, but still haven't found where this extra field gets used.

62604e8fe9 CAI related stuff (see description)
* Partially rebuild CGlobalVarsBase and CGlobalVars struct.
* Partially implement BuildAINFile (disk builder) written by BobTheBob9. All that needs to be found are the addresses/offsets for 'pUnkStruct0Count' and 'pUnkLinkStruct1Count' (see ai_node.h). I didn't have time for it yet.
* Patch call which restarts the engine once AIN file has been build (so it doesn't get cleared from memory).
* Temporarily patch write operation in 'Detours_LevelInit()' which writes out of scope since the navmesh structure is misaligned somewhere still with a few bytes.

NOTE: 'CAI_NetworkBuilder::BuildFile()' is for now commented out until the 2 other structs are found in the game dll. Once found then we could start fixing the struct offsets and hope it works as-is.
