implement new conversation list

This patch is an implementation of the conversation list using the
conversation model recently introduced in LRC.
 - Unused HistoryVC and PersonsVC are removed from the code base as we
   are switching to a one list design.
 - Setting a conversation model on SmartListVC switches the displayed
   list.
 - Actions such as selecting a conversation, double clicking, call
   button and searching are also implemented (from the LRC point of
   view which may not yet be visible for user as of this patch).
 - As the new view is based on NSTableView rather than NSOutlineView,
   a RingTableView class is introduced based on RingOutlineView code.
 - The call button at the right of the search field is removed.
