Finished adding the Action Bar with the hamburger menu

-Add the hamburger menu to each activity page.
-Created Menu files for Statistics, Leaderboard and Statistics so that
the hamburger menu could be added to these pages.
Tried to add the title of each activity page on the Action bar but it
did not work for a few of the pages. Will try to fix over the weekend
-Created an About page that we can use for instruction but this can
probably be deleted if you all think it's not necessary.
