Subject: Change dispatching approach: handlers are now part of todoItems.

Instead of dispatching the todo item in function of the DAML node's
local name at todo-handling time, the appropriate todo handler
subclass is now instantiated in the todo deque by dispatching the
creation of the todo item to the appropriate constructor.
