Teruaki Kawashima e2e7ecf350 add playback control to more menu of plugins. 
although it doesn't make much sense for some plugins like dice as the menu is only shown when you start that plugin.
change star plugin to go back to menu when exit game instead of closing plugin so that above change makes useful.

/*
Snake!
by Itai Shaked
ok, a little explanation -
board holds the snake and apple position - 1+ - snake body (the number
represents the age [1 is the snake's head]).
-1 is an apple, and 0 is a clear spot.
dir is the current direction of the snake - 0=up, 1=right, 2=down, 3=left;
