Add LST to George Area Search Modes

[LorenLuke]

Exactly what the title says:
Add an area search mode to George's current 5 area search modes, where he engages the Laser Spot Tracker to 'Automatic' for the duration of the search. Stopping the scan can be commanded with any other search, or repeating the area search, or when George finds a valid laser point, and all with appropriate dialogue to match.
