Add improved helicopter landing options to land (away from airfield) to UI (and API)
There is a new thing in the mission editor that adds options to the land function helicopters get which would be really useful, it's called combat landing. There is also a duration for landing thing already that we could do with.
The combat landing has some use because it causes the doors to open on landing, e.g. we can embark and disembark troops via the scripts with the AI units.
This probably needs to be in the UI, more than the API. but obviously being able to script helicopters to follow someone into combat with "follow" and then tell them to combat land behind them if space would be amazingly cool.
