Request to add borders for each sector on the Tyria map better help identify their areas

[TheElectricHorseman]

It would be fantastic if borders could be added added to all the sectors of the tyria maps in order that the user could more easily see their areas.

This, in principle, would be very similar to how the renown heart areas or WvW areas are presented and perhaps could be controlled as a new option on the Layers menu.

This should be pretty doable, I don't do a huge amount of changes bar keeping it updated. If I ever have a decent amount of changes to make I'll try and get it in for you.
