Hide some contacts

[krtek]

If possile, to choose wich contact to be shown in the list of the events. I have some people that i updated with some dates, but i'm not interested to see them between the names of the app list. If i push the minus button, i delete the date from the database but i wan't that. a button only to hide a date or a contact in the list.
