Added main report activity

Report page temporarily also the launcher page. We'll change that to a
dashboard soon.
This won't run for you if you don't have the google maps (see
Report.java documentation) library and actionbarsherlock library set up.
Currently the project.properties file references the paths to what i
have them saved as, so you'll have to make those your own paths
(right-click >> properties >> Android >> add both libraries)
