Reconfig fix

On updating controllers / estimators etc. the platform-specific scripts do not always update, but rather the global defaults update. If an user does an airframe reconfiguration and *selects to reset the tuning parameters to the defaults* he expects them to really reset.

This will also ensure we have a path for troubled users to really reset their autopilot (through the airframe config) and not be bothered with stale parameter values. Note that pro users and devs can just un-tick the checkbox for the config reset when re-configuring for a different airframe.

This intentionally also resets RC config and other params.
