Add marker on graph when switching targets

[ArtificialQualia]

A marker can be added to the graph to show what target you are shooting at, or perhaps what is shooting at you.

This will have some limitations. Based on the log entries, we can't always tell when a target has been switched, if they are the same corp/alliance/ship/name.

Same with NPCs, if they have the same 'name', we can't tell when they have switched.

There still may be value even if we limit to this when the user switches hull types, or when they switch NPC types.

Testing will have to be done to see how much value there is in this enhancement.

It must be user configurable.

This is a better candidate for the notification window, best not to clutter the graph with this

this is no longer needed as one can sort on damage out on the pilot breakdown
