Sector System Update

[p]This update adds the following...[/p]

1. [p]Chinook now has access to M134 door gunners[/p]
2. [p]Chinook now has access to M2 .50cal tail gunner[/p]
3. [p]Updated and fixed Chinook door gunner gimbal limits so they no longer shoot their rotors off![/p]
4. [p]Random Scenario options are now saved between gaming sessions.[/p]
5. [p]Pilot and Co-pilot selections are now saved between gaming sessions.[/p]
6. [p]Updated the default Random Scenario settings to be a little more forgiving for new players. Now the 1st time you play a mission the settings will default to 1,500 Deployment Points facing a 100pt Enemy Force Strength. [/p][p]This should give a much less punishing mission for new comers and allow them to deploy pretty much whatever helicopter/weapon load out they wish while they learn how the game works.[/p]
7. [p]Sector's now respect the Enemy Force Strength setting when deploying forces. This is calculated as a ratio between selected Enemy Force Strength and the Sector's air and ground defence levels.
   
   A 500pt Enemy Force Strength is considered a hard bur fair mission level and is the baseline that I use to when comparing difficultyːsteamhappyː[/p]
8. [p]Fixed a distance calculation error which would sometimes prevent trees and ground detail from being displayed when transitioning between terrain tiles.[/p]
