CAI related stuff (see description)

Browse Source 
* 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.
