Added 'selected' png's for each icon type. Enlarges and borders the icons, for ease of use.
Merge branch 'master' of https://github.com/ctstrope/306Final
Refactored to remove unused class, and to change uses of RescueLocation to Points (we may just nix RescueLocation, it's functionality is not important...yet?). We implemented selection of team icons, and clicking on the map when not updating team locations.
