Added in-game analytics. The main purpose of this is to eventually add "winnable setups only" option which many players have been asking for. Mathematically it's very difficult (maybe even impossible) to calculate "winnability" of a given solitaire variant, especially if there are 120 of them with different rules. So, instead, the game will now use analytics to note which initial setups have led to won games by real players. After enough data is accumulated, in a later update I'll put it into the game, and you'll be able to play with only the winnable (and not random) setups if you wish so. Of course you can opt out, and no data will be gathered from your machine. Still, if even a small share of players are okay with this, eventually the game will have a working "winnable only" option. Thanks!
