marking the last move
Review Request #125506 - Created Oct. 3, 2015 and submitted
Because there is no animation for move, it's not immediately clear where the oponent played. This patch adds a second stone type which is used for the last move.
Sascha hasn't done any commit since 2010, so this is one of the manu unmaintened stuff we have.
If you really think this is a good thing, commit it (maybe wait a few more weeks in case anyone else bothers to comment)
