Added World Map Function

I noticed in the world map you can press 'alt' and hover over areas to see points of interest, bosses, etc. I think it would be a great addition to be able to hold alt and hover over the 'Act 1' banner at the top of the world map and have it display all of the points of interest, bosses, etc, for the specified act. That way you don't have to hover over each area to see if you have cleared it or not.
