Added a new type of background to the tree stump, a forest floor with dried pine needles and some leaves. Like the others it is also randomly generated each time you click on it.
Added a button to the in-game user interface in classic mode to change the color scheme. This was only possible in the menu before.
Previously, if you clicked on "Invite a Friend" while the computer player was thinking, it would not be interrupted and would still make its next move. This is now fixed.
