Improved optimization with distant AI

AI teammates can also now use grass for concealment. Their system is much more rudimentary than the player's, they may only be concealed when crawling through the grass.
Also, made another attempt to account for INDFOR civilians.

Reverting back to preINDFOR change as some users reported slowdowns.

Changed the logic so that when fighting INDFOR civilians do not take up computation threads.

Improved compatibility with some other mods such as DRO (Dynamic Recon Ops).

The multiplayer signatures were tested on a sever (big thanks to @Gunter Severloh!) and appear to finally be working. Make sure you delete the old bikey files and use the bikey from the current version (ACSTG_2.bikey). The mod needs to run on both the server and the clients.

New version, new bikey :) The previous version of the mod had a function that could not be used in multiplayer, I suspect this led to the bikey conflict problem. The old bikey was named ACSTG.bikey, the new (current) is ACSTG_1.bikey, still the in the same "key" folder.

Removed reliance on SetObjectScale, the mod now works in Campaign missions and not just Eden Editor. Other minor improvements, including better detection of Altis grass.

Deleted old bikey and signatures, created new set

bikey attempt 3. Wel'll get there :)
