Extended the PokerDemo client with a prototype implementation of new button "Show client sums" that will eventually allow showing the prepared totals before and after a game.
Fixed a real informational message for the Show Client Sum command, replacing the placeholder.
Added class GeneratedTotals as a nested static class of the RequestGenerator, accumulating the amounts of all initial balances and deposits during preparation.
Added class ServerAggregation, used to receive and represent aggregated values from the servers (for example, account totals).
Made the (hard-coded) configuration flag runMsSql internal rather than private.
