Update 1992/kivinen

When I started the program I noticed that it ends very quickly. Yusuke
Endoh provided a patch that calls usleep(). I felt that this was too
slow so I added a macro at the Makefile, Z, default 15000, so one can
reconfigure it. Thank you Yusuke!

I also noticed that when starting the game it moves towards the right
and then exits. Yusuke pointed out that if you click the mouse it moves
back towards the centre. I added this to the bugs.md file. Thank you
Yusuke!

Fixed formatting of README.md file.
