Added new Layout "map_activity.xml"

The new layout has an image of GGC. I ran into a problem with size of the image being to large the first time I tried to load run the app. This update has an image size what will run on older devices(the file size smaller then I wanted). 

Also there was a type-o with the name of "MapAcitivity". I changed it too "MapActivity", and the manifest was updated to deal with this change.
