EventsListActivity: modified ListView layout to display an arrow to the
right of each item so as to suggest to the user that the items are
clickable (One might think it's pretty obvious. Who would have thought
that you could interact with the UI on a touchscreen enabled device?
Maybe next time someone complains that they couldn't have known that
something on the screen is clickable I'll set a tutorial AlertDialog on
each Activity...maybe with pictures in order to not confuse some users
with too many words).
