Log Message:
gomoku: fix error handling when reading moves from a file

The columns of the board are labeled from A to H and J to T, which makes
I5 or i5 an invalid coordinate.  Previously, reading this invalid
coordinate from a file resulted in the string "<6" appearing in the move
log.

The 'i' was converted into the nonexistent column 20, and PT(20, 5) got
an out-of-bounds argument, resulting in spot 120.  Converting this spot
back into coordinates resulted in PT(0, 6).  The '<' comes from
'letters[0]'.
