Use a dynamic method to print recurrent items to stdout

Add print_recur_apoint() and print_recur_event() helper functions to
print recurrent items to stdout and use them everywhere. Currently,
these are only wrapper functions to print_apoint() and print_event()
that create temporary, non-recurrent items.
