Added handicap to the computer-go interface
I added the possibility to play with handicap against the GnuGo computer-Go program, online. This should make games more interesting. Link to computer-Go page here.
Also, I owe an apology: I have introduced a bug that resulted in the board not to be displayed at all for the InternetExplorer users for the last few days. Fixed now. (By the way, why not use Firefox instead of InternetExplorer?)
