1.85 bug fix patch

- Added snap view rotation degree settings.

- Changed the way Air patrol mode works : You only need to pass 2 patrol points, and only the current target patrol point gets displayed on TSD as the third waypoint to reduce confusion.

- Added slight damping  to the infantry and M60A2 gunner's aiming. If you steer the helicopter too quickly, the gunner won't be able to shoot enemies. You need to stabilize the helicopter to let the gunner aim the enemies properly.

- Mi-24V hinds use 9M114 Shturm while flying forward without hovering.

- Overhauled player's Squad management to allow dynamically removing and adding new units for future plans and fix these issues :

1. Ai wingmen sandwitching you if you take the wingman's  helipad first.

2. Various bugs when the dead wingmen get resurrected in the main base

- Some optimization works :

1. Reduced the vertices of tree models and overall number of trees spawned in the world.

2. Fixed the player's CCIP calculation to be more efficient to prevent frame drops when calculating long distance.

- Fixed various minor bugs I have found during play testing.

The 1.8 version is now more stable with no serious game breaking bugs as far as I can tell. now I'll focus on 1.9 update.
