Changes to off-block logic / offblock time vs. flight time

[Henrik]

A nice idea would be if off-block starts when your aircraft either starts an engine, or has been moving for more than 5 seconds which would mitigate off-block times starting due to smaller movements due to GSX etc. etc. It would also be nice if there was an option to show total block time instead of total flight time on my profile as an option. Some people (including me) care more for the Block time than flight time, as that is what we look at and log in our logbooks IRL
