connected addEvent w/ chosen date&time
changed name of .dateTimePicked have to fix path. wonky if i choose a past time
.sortTime() works, now to add it into a service, and invoke it every time
added sortTime to filterLifeEvents in services, now need to make it its own function to be returned in obj
added sortTime as a method on filterService, used in .addEvent
deleted buttons used for testing checkDate + sort
