[CA] [CA11] LH3 data backup

[danderer]

This may well have been suggested before but I'd like to make sure it makes it to the product roadmap--it is important to me and I suspect others.

LH3 allows the users to backup and restore data, but AFAIK only waypoints, routes and tracks. There is a lot more data I've got in my Axioms:

Boat configuration
Wifi configuration
Quantum connection
Alarm configurations
User profiles
Multiple app pages, each with one or more apps, each with their own configuration settings.

If something random should happen and this gets lost, or I have to do a reset as part of troubleshooting a problem, recreating this data will take a LOT of time (and I will still miss come pieces). That is a lot of pain.

There needs to be a way to backup/restore all the MFD and system configuration data.
