Added an Extensions to Alarm for detailed status/substatus reporting.
Extended Alarms are the first in the Alarm structure and have corresponding fields in Status and Substatus structures.
Also added a filter to the HWsettings update to prevent to block arming when actual settings have not changed.

The only downside is that it needs to update on the TaskInfo object which means
since htat updates periodically this code runs more often that really needed since
the modules only start at first. However, leaving that connection out means it
misses the initial set of modules.
1. If a flight mode switch allows autotune and autotune module not running
2. If airframe is a multirotor and either manual is available or a stabilization mode uses "none"
