Add map locations and screenshots to make finding things easier

[wizage]

This will take a while and should be made on a separate branch and will be pushed after beta/soft launch.

Using only a map image you can draw squares on top of it to determine locations of various items and pokemon. Also you can add interactivity to hover a route and get the pokemon list back.

Screenshots might be useful for some daily items like the hidden items in the game corner room.
