Asobo please add panel type assignments

So far there are no assignments for any K events that use the panel option.
For example the heading bug will not update to the current heading for older
type mechanical gauges. Basically non glass. Need assignments for K events
like: AP_PANEL_HEADING_HOLD AP_PANEL_ALTITUDE_HOLD AP_PANEL_MACH_HOLD
AP_PANEL_SPEED_HOLD AP_PANEL_VS_HOLD There may be more.
