Fix bug in board randomizer

- The board randomizer did not account for dice files that don't contain an exact integer squared number of dice. For example the 5x5 dice file contains 26 possible dice since 1 extra die is provided.
- The fix takes the square root of the number of dice and takes the floor of that number as the total number of dice to choose.
