Better date/time formatting in event list
-EventListItemInflator will now generate date time formats differently for events that span multiple days and/or are all day events:
-single day, all day
    field1: <begin date>
    field2: 'All Day'
 -single day, not all day
     field1: <begin date>
     field2: <begin time> - <end time>
-multiple days, all day
    field1: <begin date> - <end date>
    field2: 'All Day'
-multiple days, not all day
    field1: <begin date> <begin time>
    field2: <end date> <end time>
