Review request for Plasma.


Summary
-------

This patch fixes an off-by-one error which led to accessing memory just outside 
of the cells array. It also kept the first character in the cells array from 
ever being displayed on the board properly, and a bunch of crazy math to keep 
the rules of the game intact. (The last cell displayed was reflecting the state 
of memory outside of the cells array.)

Testing
-------

Aside from the initial test cases which were used to confirm the bug (hard 
coding one char in the cells array to always be 1 and moving it around to find 
the bounds of the display,) I also generated a few other board states manually 
using examples found here:
http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life

"Blinker" and "Toad" were two that were used to test.


Thanks,

obby
