Followers and Location Specific Backgrounds

In this update, I changed two major things.

1. When you unlock a new party member, you must click on their sprite in order for them to follow you. While they are following you, you can equip them and use items on them in the menus, and they will aid you in battle.
2. Since I made the "navigator" it became possible to use location-specific backgrounds. So now, when you get into a fight in a navigator-recognized area, the background will roughly match where you are in the battle scene.
