- removed friendly AI from defense missions
- made defense levels easier to acquire (no longer requires years to research)

Removing AI from defense missions was a not my first intention, but doing this seems to prevent the enemies from spawning in with 2005 units on day 1. Enemy should now (finally) spawn in with the correct year in both defense and attack missions.

- cleaned up conquest inf files a bit
- gave syria map a long haze distance
- updated mission file for "northair" conquest map

- changed up conquest defense AI a bit, here are the following changes,
--- now only tier 1 troops will be in defense
--- 1 star missions will only have weak AT weapons and 1985 tier 1 troops
--- 2 star missions will have better AT weapons and 1995 tier 1 troops
--- 3 star missions will have the best AT weapons, snipers, and 2005 tier 1 troops

- increased spawn rate for enemys in conquest slightly

- all soldiers and vehicles now emit heat when shown through thermal
- lowered haze distance on some maps so its not so laggy
- removed fog of war when in 1st person view

- updated bmp-2 and bmp-3 armor

- fixed vehicles not firing on the move (a couple of updates ago, I accidentally broke this feature)

- updated frank's "ukraine small" map

- added frankthetank's "Ukraine Small" map to battle zones

Improved AI behavior in vehicles

- AI will not shoot until aiming at the enemy now
- AI will now wait a few seconds before opening fire on an enemy

- lowered brightness levels down on the desert camo for abrams
- lowered brightness levels for some maps environments
- lowered speed of javelin missile to make it more controllable for AI
