fix missed call of "DrawTaskAAT" in multimap top view.
Draw useful info for landing aside glide slope bar
GA Task: start at departure, remove start-end popups, draw WP lines
fix EKF wind, not initializing the matrix when activated when already flying.
Resulting in assertion error. More prefilters, and removed ring buffer
Reset the matrix after 3 minutes of no sampling. This can happen expecially after a thermal.
But in such case, we normally have the wind from it. Or we climbed, and wind has changed at new altitude.
HSI: when landing display vertical speed in Ft/min
Wind with EKF more filtered. No good results below these parameters.
After 10 minutes of flight, or a couple of circles, the EKW will start giving results, not earlier.
