Double Board placement on textual interface isn't usable

[ctm]

Make it so the double-board does not start out in the upper left hand corner in the textual interface

Even though the board is draggable, not everyone knows that.

The problem wasn't starting out in the upper-left. The problem is that "chowaha mode" was getting invoked and that causes the middle two rows (which are the rows that we use for Double Board Omaha) to be shifted upward.

"Chowaha mode" is a hack, but it works fine for what it does. It's just that I used to detect it by looking for more than three rows, but it wasn't actually counting the distinct number of rows, it was just looking at the maximum row used and that caused the Double Board to improperly invoke chowaha mode:

Deploying now.
