Remove nested for loops in several files in /examples/

[Afwas]

In a few [...]PBN.cpp files there is a nested for loop:

for (int h = 0; h < DDS_HANDS; h++)
  for (int s = 0; s < DDS_SUITS; s++)
    strcopy(DDdealsPBN.deals[handno].cards, PBN[handno]

This is needed in the [...]Bin.cpp files where the cards are copied one by one. In the PBN files this is not needed because here it is a simple string copy (the PBN string).

I'll try to add a pull-request to this issue.
