Sector System Beta Update

[p]This update addresses a few bugs...[/p][p][/p]

1. [p]Turning off enemy threat circles on the mission planning map would cause newly detected SAM & AAA units to not show their threat circle on the TSD/Radar screen.[/p]
2. [p]Cockpit dashboard clocks now show the correct in game time rather than just the time the mission started.[/p]
3. [p] Updated some installations to hopefully fix the Allied/Neutral buildings appearing in some enemy installations.[/p]
4. [p]Updated the A.I. landing code to make a more positive landing attempt which hopefully eliminate an issue where they would almost touchdown, but not quite, and then drift around the landing waypoint.[/p]
