Fixes and work on console wrapper
Player.java
    + notifyDroppedCardValues(...) abstract method
 ConsolePlayer.java
    + notifyDroppedCardValues(...) implemented
 GameServer.java
    + dropSameValueCards(...) now works not with the current player, but with it's argument and returns List<CardValues> being dropped
    FIX the situation when a player gets 4 same value cards on deal: he will just drop them
    > StartGame() > players will be notified about dropping same value cards
