Remove probable bug status from 1987/lievaart

As I guessed the reason the game did not seem to work right is not
remembering how to play the game.

I added two INABIAF points to the bugs.md file as well the README.md.

-This might not work right. When [Cody Boone
-Ferguson](/winners.html#Cody_Boone_Ferguson) runs it he gets something like:
-
-```sh
-$ ./lievaart
-Level:5
-You:2
-You:3
-You:^C

-However he also hasn't played Othello or if he has it was a very long time ago,
-so maybe he's doing something wrong.
+Two issues to be aware of: if you input invalid input (as in invalid characters
+like `.`) it might enter an infinite loop printing the same thing over and over.
+Also if you don't enter a valid number it will prompt you again.
