Grid ownership and commands should rely entirely on the owner of the classifier

This would help with several situations, namely:

• Unlicensed debris crowding the fleet info
• Stolen ships taking room in your fleet - people would need to grind down the classifier immediately to avoid being tracked
• Having to have a "main cockpit" to use commands
• Overall simplification of the role of classifiers, making them seem more useful
• Ships would be a bit more difficult to steal - protecting your classifier could be an interesting design motivation

However, to do it we first need to warn people better that if they don't take over the classifier of a ship they're stealing, it can be tracked. Putting this in /gc help is not enough. Most people taking ships will get into a cockpit on it early on (in fact this seems the best correlation and why we're using it now). We can warn them then like:

"Warning: Someone else owns the Hull Classifier on this ship. You must take it over or you can be tracked"

or

"WARNING - LOJACK ENABLED"

something like that.

Let's make this an optional (but default ON) setting, retaining the current logic for now in case people prefer that down the line.
