FS#2048 - sliding puzzle plugin bug

there is a bug in the shuffle algorithm which causes the
puzzle to be unsolveable sometimes:

1 2 3 4
5 6 7 8
9 10 11 12
13 15 14

  1. - –

it is impossible to swap only one pair of numbers without
swapping another. So this constellation is not solveable.

So it has to be checked if the number swapped number-
pairs is odd or not.

There is a check for solvable puzzles, but it turns out it
used the wrong number of tiles. This is now fixed.
