Implement new features for cli.py 'event' command.

* The user can now create a new event with a not defined end date.
* The user can now edit the name and the start and end date of a given event.
* The software can now check if the event the user is creating or editing
  is overlapping another event already present in the database.
* The software will allow the shortcut keywords 'now' and 'none' in the
  'event set --end' command.
