Fix #1476 by updating the search interface

- Removed "Everything" choice for search, default to "Events"
- Add radio button for search type selection (events, activities, groups)
- Label now have a cursor pointer
- Remove the confusing concept of EVENTS, SHORTEVENTS and LONGEVENTS. There is only EVENTS and LONGEVENTS.
