CRIT: On EASY, add a pause

[hackerb9]

When playing the easiest level, if I explode a huge chain of cells, the computer plays immediately and the explosions appear to continue but are now turning the cells black. If the player just caused a chain reaction, there should be a pause (on EASY) before taking the next move.

I don't understand. The computer always plays immediately, and it doesn't start the computer's turn until all the chain reactions are done.
